re: Best Health and Fitness Wearable Tracker

I use a Garmin Fenix watch, the 6's are reasonable since they introduced the 7's. It tracks Rem/light sleep/deep sleep and restlessness. It also tracks heart rate and heart rate variability. I think it can track pulse O2 but I don't use that function. I also use it to track bike rides, hikes and runs. It has good maps so I use it as my back up navigation while hiking.
