Default Gear 2 / Gear Live comparison thread

To make it all a little easier for the consumer to make an informed decision I think it would be useful to build a comparison thread.

This is not for slating or making big statements about Samsung strategy, literally feature and technical comparison.

I.e music : Gear 2, ability to store locally and play through device or phone. Gear live, ability to control music playing on phone.

Please post any areas you know are 100% true and I'll update the first post.
