From the numerous reviews I’ve seen so far. Pixel watch is still a work in progress product. Tic watch seems promising but they have a habit of abandoning their products after a year. Galaxy Watch 4 and up seem to be promising enough with progressive updates and the platform is built on a relatively newer, power efficiency soc. Samsung is planning to use an updated version of the same soc in Galaxy Watch 6 series this August so unless they completely bail on WearOS 3.5 and up, it’s a safer bet to go with Galaxy Watch 6 in less than two months.
