KDE was never my cup of tea - it more configurable than Gnome but I always liked the Gnome look (well 3.0 that is, 2.0 wasn't that attractive to me).

Nowdays I need to develop stuff that deploys to iOS so I'm kind of stuck on a mac.

Gnome looks a bit like you got stuck in an alternative reality where MacOS evolved slightly differently.

KDE looks like you got stuck in an alternative reality and Windows 7 evolved differently. (And Windows 8/10 never happened)

I never really cared for the Windows UI.
