Joker, let me ask you a question that you might seem trivial, but is important. First what didn't you like about Ubuntu?
I would also recommend that you check out a few different distro of linux, the main ones that people use are Fedora, SUSE, PCLinuxOS, CentOS, Debian, Gentoo, and Mandriva. There are many others take a look at linux.com
for others. I would recommend that you burn some livecds and see what makes sense for your tastes, as we all have different ones.
