re: Which team here has the best logo? the worst?

To be honest, I like that newer (?) Bama logo better than the more used script A.

I'm biased but I think the interlocking AU is very solid. I love logos and branding, and it is a traditional but very recognizable one.

I like the UK one too, it is slightly more classic than AU's, but I also think it is a little more bland. There is a thin line between traditional and something that doesn't convey a modern, national brand. Ole Miss (script) for example, is really beloved down here, but I think it has little "logo power" nationwide because it is a simple script word logo.
