Moto 360 owner and Microsoft Band.

I won't echo the sentiments of the other comments but you may want to explore the Microsoft Band. It falls short on bluetooth music player. However, whether iPhone, Android or WP, you have cross-integration. Something not afforded by the other main products currently (though, rumored Wear will interface with iOS). The ergonomics of the Band needs minor improvements. The dedicated GPS and range of sensors is mostly in a class of its own. Dedicated GPS is only on the Sony Wear as far as I recall.
