Used both and I prefer 10 better. Might be because 8 was too much change all at once and soured my choice in its use, and Windows 10 is similar to 8, but better layout.
I had a laptop with 8, hated it. Tried 8.1 still hated it because games such as World of Warcraft had an issue with flight controls that wasn't resolved until I downgraded to Windows 7. I then recently pushed 8 back to this laptop and used the free upgrade to 10 and Windows 8 still had flight control issues in World of Warcraft, but Windows 10 is like Windows 7 and flight controls are correct and I have to get use to 10 to be able to support it. I've experienced 8 and 8.1 to support it when I need to, but I avoid it still. I do like Windows 10, but not as bad as Windows 7. I also like XP, although its days are numbered.
