Fanatical has 3 tiers:

1. Beginner Box, GM Screen, and Threshold of Knowledge
2. Player Core, Troubles in Otari, A Fistful of Flowers, Big Trouble in Little Absolom, character sheet packs, and the flip map for TiO
3. GM Core, Player Core 2, Monster Core, Abomination Vaults (PF2e & 5e), Rusthenge, Fall of Plaguestone, Crown of the Kobold King, A Few Flowers More, and a bunch if pawns and maps

I'm somewhat confused by some of these titles, because they're Free RPG Day releases, but I've heard they're no longer accessible on Paizo's website :/

Humble Bundle also has 3 tiers, and is paired up with a Hero Lab subscription:

1. Hero Lab (3 months), Beginner Box, Player Core, GM Corev Troubles in Otari, plus the old Core Rulebook and Gamemastry Guide
2. Howl of the Wild, Seven Dooms of Sandpoint, Lost Omens: Divine Mysteries
3. Monster Core, Wardens of Wildwood, Curtain Call, and Seasons of Ghosts

As usual, higher tiers include everything in the lower tiers, too. The Humble Bundle top tier's a little more expensive than the Fanatical top tier, but Seven Dooms, Seasons of Ghosts, and Divine Mysteries are some pretty heavy hitters here. The only thing one would really be missing is Rusthenge.
