My experiences are limited to phpBB, myBB and vBulletin. I don't like vBulletin at all. Everything feels always as though it is in the wrong place. I'm always looking for posts. It also has too many bells and whistles that always seem to trip me up.
I'd say phpBB and myBB are both great forum platforms. I like it that they are simple and easy to install. PhpBB comes with a longer history and experience, but myBB is a bit more creatively designed. For ACP I prefer phpBB. But I'm happy and comfortable with both platforms.
