[Samsung Gear S2] gordonzhao:
I want to start by saying I've only had the moto 360 as a smart watch and can only base the following on that.

Where are you located, the day of launch, all the best buy stores I called had the sport in black, but I'm waiting on the classic.

As a 360 owner, I don't think I stuck with any of the apps I downloaded, just stock was fine as it's an extension of the phone so notifications was the main thing and voice commands, primarily everything I do can be done through Google Now. The update of Hangouts was really nice though since it can be pulled up without having to get a message. but that's android wear, back to this. What apps are you looking for you feel should be available?

I think you'll have to wait for people to release a custom watch face maker like "facer" (android wear) in order to get to that level of customization. From my experience, I've tried a lot of faces that resemble real watches and custom designs, I went back to the analog watch face with a custom picture, keeping it simple was the best for me as I didn't want it to look too busy.

Is there no light sensor? also if you get a notification, wouldn't it vibrate?

the clickwheel idea would be a good improvement for the next one. it would make the selection a bit easier, rather than using your finger, but then it would defeat the purpose of having a touch screen too. which if that were the case could potentially save A LOT of battery life.

the non-3G versions don't have a speaker. I believe the 3G one does (source needed)

I think that is across the board with all watches, I notice mine sometimes but other times if I'm moving around I never notice it as I'm focused on something else, unless it's a call which is repetitive vibrations. Doesn't bother me though as I'll flick my wrist to see if there are any notifications.

the material between the wall and bedroom can significantly weaken the bluetooth range, though I've gotten a good 20-25 ft (under estimating a little) with my 360 from my phone.

notifications disappearing; what do you mean? They pop up once and then disappear without you dismissing them?

Just got my classic today, I'm not having this issue unless I manually remove the notification (swipe up)

I'm hoping the clearing of the notifications is just a glitch, though I recall that on the earlier Gear models as well. Android wear luckily doesn't have this issue.

Notifications are clearing on my end just fine, swipe up.

Compatibility for apps is still being worked on I'm sure. For example pandora on android wear use to work, now it doesn't any more; for songs it would be able to adjust volume, next, thumbs up/down. But now it doesn't work though I heard it's pandora's fault for not caring about it. What notifications are you not seeing on your watch that are on the phone?

I agree as far as the sport model goes, but the classic looks a lot better imo, as it has a wheel with ticks (nubs?) on them. I've seen the classic in person from a samsung rep and it does feel and look really nice. Coming from a gen 1 360, the smaller screen doesn't bother me as the watch is overall a bit smaller and I have smaller wrists so it's a win win.

Compared to your experience which you said you've only owned a pebble for a few days, have you used any smartwatch extensively?
