I personally do not like euther of them except for the fact that they are both very secure. But i think that to many people have them and that they are a little over used. My boards are pretty common but tghey are not used nearly as much as Invision or PHPBB. And for all of you that aer ecurious I am running the WhiteFyre source. I think that it looks a little better than the rest of them and is a little easier to use than the rest of this.

I have been using invision board for some time now and like it better that phpBB. Even the look and feel is good. The only thing I miss is its integration wrapper with mambo, since my site runs on mambo. I have to open it in separate window.

PhpBB is frickin awesome.. IPB is okay, I don't really like it too much but I've used it before.

as for the BB you're using. It's plain ugly, sorry to say. I look at it and cringe, takes my mind a couple of seconds to figure out whats going on.. :/
