I'm really, really impressed by my Huawei GT2 so far. Bargain next to £350 Samsungs and the like imo.
My two minor 'gripes' (both of which I knew before purchase) are that you can't pay with it via NFC, and secondly that there's no skipping rope activity (yet there are all kinds of random martial arts!).
To get one that works with Google Pay (I'm with NatWest who don't support Samsung Pay) meant looking at TicWatch, which are more expensive and whose battery life is inferior to the GT2.
There are loads of watch faces to choose from in the Huawei Health app. I've settled on 'Steel' at the moment.
