I know there are some people here who can give me some information. I'm in the planning stages of a community centered site and I'm wondering what opinions are when it comes to phpBB vs. Vbulletin.

I don't mind paying an ownership license for Vbulletin, but I want to know if it's really worth it. I've read that phpBB is less secure, is that true? I wouldn't have a problem updating fairly often if that would help security wise.

So I know it's a broad question, but any opinions/knowledge would be helpful.
