What are the best atmospheres for “pure college football”?

Curious what P4 stadium atmospheres are the best “pure college football” experiences. Just came back from the cotton bowl and it was the antithesis of it. Ads the whole time, hype music between EVERY single play. Sugar and Rose Bowl were better IMO.

Went to Texas@Michigan this year and was shocked how there were 0 ribbon board ads, 0 ads on the big screen, just the bands, the crowd, and football. Any other atmospheres similar to this?
