Which is the best Forum Script for large Forums?

If you would have asked this question few years back then I would have recommended vBulletin.

But now my answer is Xenforo. Its a state of the art script if you have to manage and run a large forum.

Xenforo is the best. I mean look around you all large community boards uses it.

Xenforo and vBulleting both are great. And both have pros and cons so you have to decide yourself which one is good for you.

For free mybb and for paid its Xenforo.

phpBB is the best forum script for large forums. Millions of people use phpBB on a daily basis, making it the most widely used open source bulletin board system in the world.
