I did quite a bit of research before deciding on this watch. It was between the Zenwatch 3, Fossil Q, Huawei, and Moto 360 2nd gen.
I've had this for a few weeks now and I wear it almost everyday.
First, the price wins compared to the rest. This is the best bang for your buck right here so far. Sure it doesn't offer a heart rate sensor or built-in GPS, but to me those are more for outdoors/fitness tracker type of watches. Plus, I hear the heart rate sensors aren't that accurate right now.
Second, the HyperCharge feature is what I really liked. They're not kidding when they say you can get 60% in about 15 mins of charging. It's great for a top off in the morning if you need it. The battery might seem horrible at first, but give it a few days to a week and it'll become more stable. After about 12-14 hours my battery will be down to about 55%, maybe even 60% with medium usage (I fiddle with it a lot). Battery life will depend on your usage, how many apps you have notifying you about things on your watch, and even the kind of watch face. Some faces that have a lot going on just use 1%-3% more an hour from what I've noticed.

Other Pros:
-The speaker can get LOUD! The microphone does well too and people have said they can hear me very well.
-Screen is snappy and touches are accurate.
-Top and bottoms buttons can be customized to open whichever app you want on the watch.

Cons:
-Custom band connector. It doesn't allow to lay the watch down flat either due to a plastic piece inside the edge that keeps the band curved. So with that, you'll have to wait on 3rd party suppliers to make bands tailored to this watch. **If you are good with an Xacto knife, there is a Reddit user who cut a 22 mm band to match the shape and used a 14 or 15 mm pin to fit it! Looks great too!**
-Gold ring and color of case can make it difficult to make to your outfit. Not a big deal though.

Overall, solid watch. With the processor made specifically for the watch and its great battery life, Android Wear 2.0 will only make this better.
