I tried out a Moto 360 2 with my Nexus 6 last year, and it sucked. Android Wear is just a second or third rate platform (My Pebble was/is wayyy better than the 360) and it lacks so much when compared to watchOS or PebbleOS (RIP). I had constant BT disconnects, and no matter how many of the troubleshooting steps I did, still had problems. I had random rebooting, lagging, and frame drops when doing the simplest of tasks like checking the time. The App selection on Wear is complete garbage. All it has is a bunch of fitness trackers, water intake monitors, and watch faces. That's it. Wanna check sports scores on the ESPN app? Oh wait, it doesn't have one. How about control your GoPro from your watch? Can't do that either. Delete emails? Can't do that, there's no native client, and the alternatives are shoddy at best. And the list goes on.
The Apple Watch is the king of the smartwatch market, hands down. It has the best build, the best software, the best app selection, the best ecosystem, the best integration with my other devices/Apple services, is extremely reliable, very consistent, and hasn't let me down once since I got it on launch day.
