PCLinuxOS was one of about ten distros I tried before deciding on Mepis. It is OK, but I liked Kanotix better and generally I feel more confortable with Debian because of apt and synaptic. Ubuntu is beautiful and different because of Gnome, but it is still too much like the old Linux for me (configuring and using the command line a lot), but that should change with newer versions. I just tried Mepis 3.3.2 beta and it rocks!
