I guess that all depends on how you define better. The Gridiron board on Phog.net is clearly more popular than KUsports.com Huddle. A random sampling yesterday of topics for the day around noon came up with this quick stats rundown:
Grid = 8 new topics / 451 replies to those topics / 10,157 views
Huddle = 7 new topics / 49 replies / 2,018 views
So is bigger better? Not necessarily. Since it's my job to troll both boards, I can say that you have to wade through less "crap" replies on the Huddle and generally the same general KU football news links hit both boards. The reader topics sometimes diverge and both boards have guys that know their stuff.
On appearance, the Grid is nice because it adjusts to fit your browser. Very nice when posters pirate professional photos. However, there's something clean and simple about the Huddle that makes for a pleasant experience.
Okay, so you want a final opinion. It goes back and forth, but right now I lean toward The Huddle because there aren't 900 topics pinned to the top. For me, it's all about the content and the ease in getting to it.
