I never cared for vBulletin it wasn't compatible with clipbucket
I prefer vBulletin. It's easier to find themes and other things, also it's easier to setup. Both are very good in my opinion, which makes it hard to choose, but vBulletin looks cool. My choice is vBulletin most of the timeIm starting a forum soon and would be greatful to know which one is better - but have been told IPB is the best.
