Oura for measuring sleep. Garmin for tracking physical exercise. Oura always reflected the timings and my feeling much closer than Garmin (Enduro), which basically always told me I had bad sleep (started late after my last woken moments and ended an hour early).
My own thought, it's honestly best not to track sleep unless you feel you have an underlying issue. It causes more anxiety than it solves. If you're tired, go to bed earlier, adjust tech use and food consumption before bed.
