I've been out of touch with the Linux distro ecosystem for a while. My current favorite for a desktop environment is Fedora, and it seems like most major distros default to Gnome these days. They may provide KDE, but KDE seems to be a second thought for them (which later shows in how well-integrated other pieces of the system are).

So, question: is there any major distro that defaults to KDE these days? I think openSUSE used to... but I can't easily tell if it still does, nor if it is "major".
