The Moto360 may be a wasted drop, as the Moto360 "2" is surely going to come out soon... meaning a drop in price would be counterintuitive now, if it'll happen soon anyway.
I have the LG G watch and the Samsung Gear S, G watch is quality, and I still use it for alarms, sleep tracking, etc. The moto 360 is no doubt much better.
Samsung Gear S is a bit garbage, but is a standalone phone on the wrist, and that's why I use it; less shit to carry around.
G Watch R is really a step above the moto360. The only change I would make to the G Watch R is going with QI charging like the 360 over the pogo pins. Other than that its a much more modern from the POLED display to the much newer SOC
The G Watch R is just a much more sensible and robust design compared to the Moto 360. That lovely elevated glass face is just BEGGING to accidentally scrape against a brick wall, or drop on the ground and smash.
