There's probably 20 (or more) that I could list because there are a lot of good ones, but the difference between many of the well-made campaign comes down content preference.
In no particular order:
1. Kingmaker
2. Curse of the Crimson Throne (Paizo, PF1, but converting it is easy).
3. Call from the Deep
4. Crown of the Oathbreaker
5. Raiders of the Serpent Sea
Like Crimson Throne, there are a lot of PF1 APs that are really, really good, but I'd stay away from the PF2 APs as all but one (Abomination Vaults, maaaaybe 2, have been garbage.
