I have both a Moto 360 and an Apple Watch 38mm Sport. I like both for different reasons, but Apple's effort wins space on my wrist. Moto 360 and Android Wear have some great ideas, but what is missing, for me, is a cohesive overall design and attention to details.
The two largest factors for me are how it fits me, and the fact that my primary phone is an iPhone 5 (I also have a Nexus 4 for testing/development, which allowed me to seriously try the Moto 360 and Google way of doing things).
The software differences between Android Wear and Apple Watch are significant. One of my biggest grips with Android Wear is "OK Google." While handy for many tasks, like setting a timer hands free, when it doesn't understand what I have asked it defaults to doing a Google Search. That in itself is annoying. Worse, sometimes it activates on its own and searches for whatever gibberish the microphone picked up. The results then can be downright disturbing and not amusing. I sent feedback to Google on this that the feature needs a disable setting.
Whether you prefer Google Now's predictive Cards approach or prefer to only receive information when you ask for it remains a personal preference. I found the Now cards sometimes eerily helpful, and other times a visual distraction to the watch face.
Beyond the software, the Moto 360 was a disappointment with health tracking. It often couldn't read my pulse prompting "Try again." The pedometer seems to be set up for people with a shorter stride, as it would underestimate my walking and running distances by 25-30%. There is no setting to calibrate stride distance, and it didn't matter if I took my Nexus phone with me or not. Health tracking features ultimately seemed like marketing department checkboxes rather than something that actually worked.
The round bezel-less LCD screen of the Moto 360 is striking, and it's great for analog faces. The "flat tire" where the ambient light sensor is mars the appearance, though you do stop noticing after a while. I was glad to have the light sensor, though, as other Android watches I'd seen light up incredibly bright in dark rooms unless manually adjusted. If you are the kind of person to prefer a digital watch face, the round design doesn't really have much appeal for that.
Those are my thoughts for now. Both the Moto 360 and the Apple Watch seem to have comparable battery life (Moto 360 having had several software updates that addressed initially abysmal battery life to where it now lasts a day and a half for me).
Oh and watch faces. Motorola's supplied faces are pretty good and somewhat customizable. I only tried one third-party face on my Moto 360 ("Skymaster") which featured a sweep second hand and a weather complication. Sadly, it chewed through battery life, even when not the active face. The weather sourced an open-source weather project that was often inaccurate for my area. I went back to the stock faces after that experience.
