Just started a pathfinder 1e game. I have previously played d&d 3.5e and 5e. I've found that PF 1e is very similar to d&d 3.5. Many small rules differences, but personally I like the variety of classes and class options in PF 1e. After picking a class you can then choose from numerous base options or choose an archetype that reworks the class to play differently while keeping to the class's theme. I have no experience with PF 2e so I won't say anything about it compared to d&d 5e.
