I am doing one last forum (famous last words!) and was going to get another vB license and simply use one of my older 3.8 styles, as I really don't have much time to port over or do a new design or learn another (php) forum software (I'm a Ruby guy these days! In fact the new forum is going to be about Ruby!). But that Azh! She keeps tempting me! (I like the new like system on adminextra.com) So for all of you who (and especially those who have ported over from vB) what do you like about it and why should anyone get XF over the other forum apps?
