I have been using Linux for about 15 years now. I believe the best Distros out right now are; OpenSUSE 11.2 and Ubuntu 9.10 (Note: Ubuntu is about to release ver. 10.04 around the end of the month) Both versions have a strong Linux Kernel and structure with an enormous amount of support. But if you are new to linux or just prefer an easy to manage GUI version, then I would recommend Ubuntu.
