I usually go for the classic uniforms. I did like UNC's uniforms before they changed them for next season. They aren't horrible but I liked the old ones better, and I liked how they started working in navy uniforms too.
I think LSU's purple uniforms are some of the best in college football; I know their tradition is white jerseys at home but their purples are awesome. They are kind of like the Dallas Cowboys of CFB (I think the Cowboys' navy uniforms are maybe the best in the NFL and they hardly ever wear them).
I actually like Florida's believe it or not, and I know I'm in the minority but I really like their blue jersey/orange pants combo.
