Favorite Forum Software?

What is you favorite forum software that you have used?

Out of the ones that i have used, I would have to say phpBB. Although the mods are hard to install, I find it a lot better looking than the other types I have used.

phpBB. You can do basically anything you want with it

I go with MyBB every time that I'm setting up an forum, simply because I have the most experience with and I'm able to nearly fully customize it to my likings (nearly, because at current time I'm able only to visually do nearly anything to it ).

My vote definitely goes to MyBB, Nice, easy to customize and professional.
