Ubuntu is fine for a test to see how Linux behaves, but I found it a bit boring. I would either go for Mandrake, Fedora or SUSE, but as SwordFish_13 says it is a matter of taste and what you are going to use it for.
Is Linuxiso.org really updated? I used to find many outdated distributions and broken links? Too late to check it out, perhaps I do something constructive in the morning...
