i purchased the Huawei watch 2 sport yesterday I also have the gear S3 wanted to try Android Wear 2.0 so far I am really enjoying it but it's only been a day.
I am the opposite I have a Samsung gear S3 which I happen to love and want to try Android Wear 2.0 so I just purchased the Huawei 2 have not set it up yet
specs are the same I have tic S and only difference is GPS is built into band so you can not change your band while the tic E you can switch your bands
just purchased the tic s to try android 2.0 I have a gear s3 now as my main go to watch but I am loving the notifications on tic only wished it had NFC so I could use android pay.
my first was a pebble which started me off since had gear s, moto 360, gear live,fit 2,gear s2,gear s3 and now tic s guess I am addicted also. My favorites have been gear S3 and just received the tic and liking what was done with Android 2
