Which university-related expansion pack do you love most?

My first place is Sims 2 University, it was easy to keep track of the grades, and it was pretty fun.
Second I would say Sims 3, because it felt like it took what made Sims 2 University great, and expanded on it.
Last would be Sims 4, the outfits are good, and the world is nice, but you can't see the grades for the Sims, and it can take pretty long to finish.
