I think the biggest issue for many is using it in a car? As far as I know, the watch will not pair like a phone does for calls using the typical bluetooth standards that work just fine across all conventional cellphones. Not being able to field calls in the car would make this an instant deal breaker before I even tried. If I have to bring a phone along to ensure car support, I'm stuck bringing a full-size cellphone with me most days anyway. Losing Apple CarPlay (potentially no navigation app at all in your car) will also be massive detractor for a lot of folks. If you don't own a car, it's probably a ton more feasible with how the watch functions today though.
