Best forum software - FREE or PAID

[isritter]

Hey guys,

I'm looking for the absolute best forum software out there. Security, expansiveness, layout, etc... are paramount.

Also, are there any great forum themes that look a lot like Digg?

Mybb, SMF, or vbulletin!

I've used SMF but I've heard SE's won't crawl it (at least very easily). How SE friendly are MyBB and vbulletin?

and which is better, vbulletin or web 2.0?

I'd like to know answers to both questoins please

Get vBulletin and vBSEO, will cost you but they worth.
