Haven't used Fedora 11 yet or 10 for that matter but from what I have heard from some of my Linux podcasts - KDE 4 has made some really big strides and is gaining ground rapidly.
I think KDE caught a bad rap earlier from all the hype on the KDE 3.4 release then it let everyone down.
But in regards to KDE 4
A lot more Ubuntu users are migrating to Kubuntu for that reason alone.
I used KDE4 for a few weeks and I liked it (mostly).
My problems with it:
* Kwin's compositing does not work on my laptop. I use the Open Source radeon driver which is still being developed so I'm not too critical about this, but compositing works fine in Gnome with Metacity (and Compiz works fine).
* Kwin's window borders become corrupted sometimes, again this is probably mostly a driver issue but it simply does not happen in any other DE I've tried.
* Python plasmoids were broken in F11, someone forgot some packages and it took awhile to track them down... This is really more of a Fedora issue than a KDE issue but you would think someone would have tested this before the release.
* Random weirdness? I'm not even sure how to describe this. Several times most of my desktop just disappeared.
* Some of the big KDE apps crashed several times during normal usage...
I really liked some of the KDE apps though (Karbon, Krita, Amarok when it wasn't crashing

).
Gnome doesn't have anything like plasmoids (gdesklets, screenlets just aren't as integrated). I generally keep a pretty clean desktop but having something similar to iGoogle on my desktop would be pretty nice if it worked well.
I may try KDE4 again when Fedora 12 is released. Hopefully they will do a better job next time...
