That's Pathfinder 1e though. Pathfinder 2e is even better in my opinion because it takes what was good from 1e (the world, the customization options, ...) and simplifies play enormously for both the GM and the players to be much more beginner friendly.

I never played DnD 4e but afaik, some of the greatest changes of PF2e have been in DND 4e before and didn't make it to DnD 5e.

D&D 3.75e

Incorrect. The best D&D edition is 4E, and that's why Draw Steel is the best not-D&D.
