I hated 8 and avoided it like the plague. The GUI was just too strange and different to get used too. I stuck with Windows 7 for as long as possible. For the minority that took to it, like you, they love it. Unfortunately not enough could cope with W8 for MS to continue with it.I was skeptical when 8 came out, but I learned to love it.
Windows 10 makes me feel like I am working on a rainy day.
I use XP, W7 and W8.1 as VMs, plus a couple of physical machines on W7, the rest of my machines are running W10. No there are few if any aspects of previous version of W10 that I'd want to go back to. Generally each new version has been an improvement over the previous one.I expect people to prefer aspects of previous versions of Windows 10, whilst being on the newest Windows 10.
