For me:

- Measuring resting heart rate, SpO2, etc. passively and tracking these over time and the impact of my fitness regime on them

- Sleep tracking

- Tracking pace and heart rate on a run, ride, etc. and (a) using it to manage my pace during the activity; and (d) use it to measure how my performance changes over time

- Navigation and tracking when hiking/skiing

I don't have so much interest in the tracking during, say, a gym workout.

I agree with the GP about wanting a subscription-less Whoop as I like to wear "real" watches so a band on the other wrist is perfect ("double fisting" watches VC-style is not an option I'm willing to entertain). I did like my Pebble enough to include it in the rotation of "real" watches though, too.
