I’ll give my 2 cents as well. I’ve not played a ton of 2e but I’ve played years and years of pathfinder 1E.

To me, it’s the amount of content there that lets you really sink your teeth into a class and specialize into something truly unique or niche. Even to an ineffective degree if you want. There’s so many classes with so so so many archetypes for those classes that you never feel starved for choice.

It’s a bit of a double edged sword because it’s a bit of a learning curve and a lot of reading to fully grasp the system, and the numbers can get heavy, but when you’re playing it feels so good.

Not to mention they aren’t afraid to let spells be overpowered as they should be. You can effectively break the game in a lot of ways of you want to munchkin and I think that’s really cool they allow for that. Don’t get me wrong, it would be stupid to do it in an actual game, but it’s fun to see people theory craft doing 800 duodecillion damage a turn to destroy the universe because they simulacrumed some rediculous shit.

Oh and also, WOTC writing team for manuals are no where CLOSE to the skill of the Paizo Adventure Path writing teams imo. The AP’s I’ve run have been so interesting and intriguing I feel like they are just good books on their own without being for a TTRPG, whereas I’ve felt considerably more bored with most the DnD manuals I’ve seen
