It's very much better than XP I, like Keef have it as a dual boot system but I haven't wanted to go back to XP apart from the need to use one legacy program, and now with a virtual M\C running XP installed which auto-starts when I click on that legacy program I don't need to go back at all.
There will of course be a lot of cock ups when people do an upgrade instead of doing a clean install, but that's their choice.
