I honestly find college football more interesting than pro, just for the variety of different styles. I'm very unlikely to watch too many pro games that don't involve the team I directly root for, but I'll watch a lot of college football games where I have no rooting interest, just because they are so interesting.
Sounds like you will be seeing a lot of Pac 12 and Big 12 football, so for example watching a game between Oregon(high-flying up-tempo spread offense) vs Stanford(traditional, power football with a defensive focus) is a lot of fun. In the NFL, everyone runs pretty similar styles. Sure there are different basic schemes, but nothing as drastic as watching a college team that lines up and runs 99% of the time, only passing a couple times a game(Navy, Georgia Tech, Air Force) vs a team that does the exact opposite, throwing 50+ times a game(Wash St, Texas Tech, Fresno, etc) . Just absolutely opposite ways to play football, and both can work just fine.
Seeing college teams that have glaringly obvious weaknesses, and then trying to work around that to succeed, really brings an extra level of fun to a game. There's college teams out there with QBs that can't hardly throw a forward pass, so they just run their QB like an extra running back most of the time. Or there are college teams that are small and undersized so they try to rely on their speed when they are drastically overmatched in the strength and size dept. Everything in the NFL is fairly vanilla by comparison because everyone is great at what they do. The difference in skill level between the best and worst NFL team is only a small fraction of the difference between the best and worst college teams.
