Which smartwatch is best?

Question

Which smartwatch has been the ruler in terms of its investing value for money?

Comments

Right now, the best options for me are:
Samsung Gear S2- compatible with Android and iOS, very stylish, not too expensive
Huawei Watch 2- built-in GPS, battery lasts up to 2 days
Samsung Gear S3- the best, battery up to 3 days, but quite expensive

Answer 1

Since I`m a fan of Sony, I would recommend Sony Smartwatch 2, 1.6-inch LCD display, compatible Android 4.0 or higher

An interesting smartwatch is also LG R, dust and water resistant, 1.3-inch display, but more expensive than the previous one

Galaxy Gear is a truly tiny smartphone, yet it`s exclusively compatible with Note series
