I've been a hardcore KDE fan since over a decade. Of late though, I am inclined to move fully to GNOME 3. I use KDE on my laptop and GNOME 3 on the work desktop. I find Gnome 3 much more pleasant to work with and it let's me forget about many details of doing things on the desktop. Once I got used to it, it allows me to switch tasks faster and with less focus/flow loss while doing so. It doesn't have a "minimise" button by default in GNOME 3 and at first this annoyed me but now I see that I never think of the concept of mimising something in my workflow. It's one less thing to think about.
I know there's a lot of hate for GNOME 3 floating around but I have tried it and I love it. I showed it to a lot of colleagues and most of them have switched to it too. I think in the next LTS release of Ubuntu, I'll switch my laptop to GNOME 3.
The GNOME Remix is hobbled by Canonicals decision to stick with older releases of GNOME and GTK. Ubuntu 14.04 will likely ship with GNOME 3.8 instead of 3.12. For various technical reasons they can't just put the newer version in a PPA.
