It's fair to say that no-one has truly answered the smartwatch question yet. Google's Android Wear and Samsung's Tizen OS provide two of the best options (if you don't want to go for the Apple Watch) and offer two different approaches. But which one do we like using the most?
From notifications, apps and the hardware that you can find them running on, we've spent a good deal living with both to help you decide whether Tizen or Wear 2.0 is the one for you.

Tizen v Android Wear: Smartwatches
Features and apps might sway your ultimate decision but your gut feeling on which smartwatch platform to choose will probably be based on the hardware itself. And it feels a bit odd to describe these smartwatches as hardware these days as on both sides, tech companies are doing a much better job of disguising the tech as truly wearable accessories.

On the Tizen side, you have Samsung's current flagship wearable, the Samsung Gear S3 Frontier and Classic. It's still running on the smaller Gear S2 as well.
Also don't forget about 2014's Samsung Gear S and the even more vintage Gear 2 and Gear 2 Neo which you can still pick up online. We'll focus our attentions on the Gear S3 and S2 for the purposes of this feature but if you want to dive into the details of these older models, head to our individual Samsung reviews.
If you're interested in Android Wear, you now have serious choice and that collection of Wear watches is set to get bigger. To pick out a few, there's the Moto 360 2 and the Moto 360 Sport (with GPS) from Motorola, the Huawei Watch and the Asus ZenWatch 3. The Sony SmartWatch 3 should also still on be on any Android Wear shortlist.
There's the Tag Heuer Connected at the luxury end as well as the more mainstream Fossil Q Founder as high end watch companies and fashion brands get in on the action too. Casio is onto its second Android Wear smartwatch with the WSD-F20, the New Balance RunIQ has just launched and Polar's M600 is our current sporty Wear fave to work out with.
Bottom line, if you want choice Wear is your one, but let's not discount Samsung's smartwatches altogether. The Gear S2 is still one of our favourites, and while the Gear S3's are on the big side, we'd be inclined to say it's a nicer looking watch than the Watch Sport as well.
Android Wear v Tizen: Compatible phones
A big plus for Android Wear is that it is compatible with not only any Android phone running Jelly Bean 4.3 or later but also iPhones including the 5, 5c, 5s, 6 and 6 Plus if they're running iOS 8.2 or later. While it had been a pretty limited experience on an Apple smartphone, that has since changed with the introduction of Wear 2.0. Now the Android Wear on iOS experience should be more on par with what you'll get pairing to an Android smartphone.

While Tizen had initially been a Samsung phones only setup, that has since changed to add support for Android handsets and now it's also compatible with iPhone 5 and newer handsets. As we spoke about in our Gear S3 review, you're not getting the full fat experience, but the features that do make the cut, work with little issues. You can download apps and access sports tracking, however dealing with notifications is limited.
We haven't spent a lot of time with Wear 2.0 on iOS, so can't make a judgement just how well the two OS platforms crossover, but it's definitely a positive that both can be used on multiple platforms.
Tizen v Android Wear: Interface and features
Now we get down to it. Android Wear 2.0 has landed with the new Gear smartwatches now up to version 2.3.1 of Samsung's own operating system.
For Android Wear, version 2.0 sees a big overhaul of the overall experience from a new-look UI to the new ability to download apps directly from the watch. Voice navigation stills plays its part but has effectively been replaced with Assistant, Google's take on Alexa.
Now physical hardware features like the traditional watch crown can be used to interact with the menu screens and a few Apple Watch-inspired features are in tow as well including Complications, which let's you add small widgets to any watch face.
It's a wearable face-off
Features wise, there's plenty to get to grips with including standalone calling and 3G on some models like the LG Watch Sport plus Wi-Fi support so you don't need Bluetooth on all the time. Google's services are second to none, too - Maps, Voice, Gmail and the like. Both also offer the ability to make purchases from your wrist with Android Pay and Samsung Pay available in select countries
In terms of getting around the UI, right now we prefer Tizen OS to Android Wear. It's a simple set up, more reminiscent of a smartphone screen (specifically TouchWiz) but less hectic and potentially confusing than both Android Wear and Apple Watch. The integration with the rotating bezel, too, is lovely and means you don't cover up what's onscreen with your fingers. Put simply, it relies on less of your brainpower to quickly access what you need to see and, for a smartwatch, this is crucial.
You can connect Tizen to Wi-Fi too and the Gear S3 Frontier has LTE which allows it to be used as a standalone device, for instance with AT&T's NumberSync. It's not perfect, though.
Cosmetically, the interface is a little cartoonish and Samsung's own services won't always stand up to Google's. Voice memos, in particular, are disappointing though for instance, you can get HERE Maps for Tizen which is a pretty good alternative. Speaking of apps...
Android Wear v Tizen: Apps
Perhaps because of Android Wear's slow start in terms of sales, it has had less attention from headline grabbing apps and companies. With more fashion partnerships coming to fruition, though, this could change very quickly. There is a nice line in Android Wear watch faces and individual smartwatch makers, like Tag and Casio, are pushing these bespoke downloads as a reason to choose one smartwatch over another.
It's worth remembering that Android Wear supports alerts from pretty much any app you have on your Android phone. So you may just tell us to quit our bitching if that's all you require of your second screen.

Tizen is definitely lagging though it does has Uber, a dedicated Spotify app and Nest, which uses the rotating bezel to adjust your thermostat. There are apps such as Mr. Time Maker which lets you play around or create watch faces and Samsung has a few smart home and car deals with its own SmartThings platform and Volkswagen.
But apart from a short list of big partnerships and a smattering of popular apps, it's not really clear whether devs are prioritising this OS. Plus beyond the watch faces, neither operating system is *that* customisable in terms of the look of the interface. Still, as we're starting to mull over, maybe smartwatch apps aren't the make or break we thought they were.
Tizen v Android Wear: Health and fitness
Android supports GPS and smartwatches like the LG Watch Sport, Polar M600, the New Balance RunIQ, Sony SmartWatch 3 and Moto 360 Sport have taken advantage of this. Polar has arguably come the closest to turning Android Wear into a platform for real fitness enthusiasts and there's still definite potential here
In terms of basic tracking, you can use Google Fit to track the likes of walking, cycling and running. It monitors steps, distance and estimated calories burned as standard then add this data to stats collected by dedicated fitness wearables in Fit on your Android smartphone.
Wear 2.0 also adds a series of workout challenges and standalone apps are making their way to the platform with Strava among the first to take advantage of the built-in GPS on the likes of the M600. Hopefully the likes of Adidas, Nike+ and RunKeeper will follow suit.
With both Gear S3 models now equipped with GPS, you can now use Tizen as a proper running watch. There's also a whole host of sensors including a heart rate sensor and barometer for outdoor pursuits. Automatic exercise recognition is also included and works with multiple activities while rep counting helps you keep a check on sets of lunges, crunches, squats and burpees.
Samsung's S Health platform continues to improve with every software update and feels more complete than Google Fit in comparison. As far as replacing sports watches are concerned, both still have some way to go, but we'd be inclined to say that Samsung does a slightly better job of it. If you care about the third party fitness app support, then Android Wear is the way to go.
Android Wear v Tizen: Verdict
Tizen or Android Wear is just one consideration when you're deciding whether to buy a Samsung Gear S3 or an Android Wear watch. Design, price, customisation, everything has to be just right for you to give up your wrist space for one of these devices.
If you're plugged into Google's services or you need a specific sensor, feature or finish, it's worth diving into the specifics of what each Android Wear smartwatch offers. If you've never worn a smartwatch before, you have a compatible phone and you want a device that is easy to use from day one, try on a Gear S3 or Gear S2 for size.
Also, remember - there's a whole bunch of hybrid smartwatches disguised as analogue watches from Fossil, Withings and co. This isn't part two of the smartphone race, everyone is doing their own thing and beyond Android Wear and Tizen, a startup or fashion giant might have made the perfect smartwatch platform for you.
