Like most things in life, it's a matter of preference. I enjoy the Apple Watch for the notifications and it helps me stay off my phone constantly. I just got the Whoop (yesterday) and I got it because I enjoy the data. I'm the type that goes through my Strava numbers for any long bike ride. I want to track sleep, I want to see the impact on my HRV, etc. The data motivates me to work harder because it keeps me accountable.
I think it's great that you don't need that, but I've found that I do. I'm absolutely nowhere near the level of a solid athlete, but I'm mid 30s and realize that there's never going to be an easier time to get back in shape.
