3.x was not some perfect, untouchable version of the game rules. PF2e isn't either, but acting like 3.x is this finely-tuned specimen of the game is ludicrous. That game was janky.
If you like the game (and I did!), that's fine! If you like the jank (and I did not), that's also fine. But don't act like 2e isn't worth your consideration just because it's a different game. It sounds just as ridiculous as refusing to consider a SNES because you poured "all this money" into an NES. Just say "eh, I like what I've got, it's enough for me" and move on.
