Twisting in the wind
I get to use 7, 8, and 10 daily and find that there are some very nice features in 10 - it's actually a decent desktop system that works with both conventional workstations and touch screens as well as having a number of nice features.
Unfortunately, the entire experience with 10 is ruined by its nagware and insistence on phoning home every more the user makes - I'd happily pay for a version that to could easily customize to remove bloatware and maintain some semblance of privacy.
So overall I'm waiting until Windows goes to 11.
