Upgrade from 4.0 to MG?

Anyone upgraded from 4.0 to MG after several years of use? What are your thoughts?

Im using whoop since almost 5years and my renewal is due in 3weeks. I already know I always should go to bed the same time and sleep for like 8h, alcohol is bad (-18% for me), I should train in different heart rate zones, do my 10k steps a day, etc. Is it worth the 400usd upgrade or are the new features not worth the price? Im not an athlete or something, I just love the data. And my uploaded blood tests didnt give me any new insights, as Im checking those regularly anyway.

Thanks for your thoughts!
