bbPress because it’s the only forum software I know that can be easily customized . In phpbb, VB, IPB etc… you have to browse lines of code juste to change the HTML structure, you even have to hardcode something in the core files, which is not the case with bbPress because you have powerful things like hooks, templates etc…

But of course, you need some knowledge in HTML and Php ( at least some basics ) in order to make your bbPress really unique .

All in all, I think that bbPress is the best forum software for web developpers looking to customize ENTIRELY a forum and make it really unique . Just take a look at the lame phpBB2 boards out there, they are all identical, except the headers, nothing unique, the same structure etc…
