I'm going to be installing Debian on my main desktop, that I use mainly for development and Internet use.
I've liked KDE 4, but it felt a little slugish at times and now I really want a lightning-fast stable-as-a-rock desktop. XFCE its an option, but as I really like some KDE apps (Amarok 1.4 comes to mind as one of the best applications ever made for desktop linux) I'm trying to decide
For normal desktop usage, should I go with Debian stable with KDE 3.5.9, go with Debian Unstable or Slackware with KDE 4.2/4.3, or with any distro of my choice with XFCE?
I know that KDE 3.5.X is a dieing branch, but it came to a level of elegance and stability that KDE 4 will have some time reaching to.
Am I just being nostalgic? Is it worth/possible still to use KDE 3? Should I suck it up and jump in the bandwagon with KDE 4? Should I jump ships and go with GNOME or XFCE?
What is your take on this?
