I've been using Fedora for a couple of months now, and have been loving it. Very soon after I jumped into this community (among other Linux communities) and started laughing at all the people saying "KDE rules, GNOME drools," and "GNOME is better, KDE is for babies." But then I thought, "Why not give KDE a try? The worst that happens is I go back to using GNOME."
Now I get it. The level of customization is incredible, it's way faster than GNOME, and looks beautiful too. At this point, I'm not going back.
I'll happily contribute to the playground fight over desktop environments. KDE rules, GNOME drools.
I appreciate KDE for being a comprehensive toolbox that will let just about anyone craft the mouse-driven GUI of their dreams given enough time and effort. I appreciate GNOME for its bold and unified vision, which isn't afraid to cull features or embrace innovation.
In what sense do you mean "faster" though? If you mean more performant, I haven't experienced that -- both desktops are extremely responsive.
