Update
I got to use the Huawei watch 2 bluetooth and now own one.
It was a close call between the Samsung and the Huawei! The Samsung is the better watch in my honest opinion but with Samsung pay not utilised by UK banks, one of the main samsung gear /s3/s4 features is redundant til banks allow this feature! The Samsung gear has a bigger watch face, the option to use the touch screen or navigate using the dial is a great feature. The health fitness apps seem easier to use ( might not be accurate according to the gadget show feature I just watched). The battery on the Samsung lasts longer than the Huawei, the charging stand for the samsung is better compared to the Huawei.
I'd have liked to have tried out the Ticwatch pro but sadly I could not find any shop near me that had one.
