Heh, I've made a lot of distro hops recetly. Mainly because I haven't found "The Distro". Every distro seems to have some aspects I like but nothing has them all
I'd suggest you try distros until you find one you're most comfortably with and then stick with it.
So far I've been using Slackware, Debian, Gentoo, Arch and turning my eye on FreeBSD.
Slackware's been the closest but the lack of automated package management is big minus for me as I'd like to be with the latest software. Gentoo's nice but I'm impatient to wait all the time and it feels quite beta as it has a lot of broken packages in 'stable' set. Debian is nice but perhaps too automated and Arch is just too 'young' distro but felt pretty promising one.
Just got Qemu to work so I'll start to test distro's more with it.
