Mepis

Im currently in the process of building a PC, ive got a lovely windows one ( which im posting with atm ) so i was thinking of using mepis linux on the new pc at the side, As a thing I can experiment with.
Is mepis the best or would you suggest somthing else?

I'm currently trying out OpenSUSE 10.0, and it's not bad at all. Had to add in some external repos to get stuff like mp3 support because Novell doesn't want to get sued by patent trolls, but it's all pretty easy through YaST.
