If you are on iOS, there is no better option than Apple
Watch but if you
prefer circular dials, then Samsung Gear S2 is a pick among the best.
Other people simply don't
prefer the
circular smartwatch time, and they're looking for something square, which is fine as well, the ZenWatch and Sony Smartwatch 3 are great offerings, and there are always the Gear Live and the G
Watch available if that's what you
prefer.
