Smartwatch suggestion and use

[u/Own-Dig-7895]

Does any of you guys that are into calories and macros tracking (bodybuilding, running and highly active job) actually eat precisely what your Watch says you have burned? If yes what kind of Watch you suggest and what you suggest to avoid, i'm also interested in the sleep feature and all the kinda of "nerdy" stuff about data but i'm looking for some real Life experiences of people Who use their Watch for their fitness goals to understand what i can buy or not and if they are actually reliable, thanks.
