Do you find your Apple Watch Useful?

I don’t know if this is totally on topic but I was debating getting an Apple Watch and I was curious to find out about peoples opinions and how useful they are from a health perspective, practically speaking.

Obviously I can go on the website and see what the features are but I’d like to hear from people who have used them long-term and whether it’s actually worth the investment or whether you found other or better ways to track things or keep an eye on yourself ?

Thx!
