First, I try to do my part for Kubuntu. Out of the box, I find it more polished than Debian KDE. And without Kubuntu, NetRunner Stable (laggy and feels strange to me, as if they customized too much) and Linux Mint KDE (feels OK to me but a bit laggy) would probably have to fold.
If Arch installation proves difficult and/or forums are inhospitable, I recommend Manjaro. Their forums and IRC channel are very helpful. And, while the official repos are not huge, the AUR is pretty awesome; it even includes proprietary software like google-chrome and dropbox. That said, Manjaro, too, seems a bit laggy. For me, either on a netbook or in a 1GB VM, Kubuntu just feels like the lightest KDE distro.
