When it come to more traditional RPGs, I really like Pathfinder 2E for the following reasons:
- It scales very well from level 1-20. The math just works
- Encounter design and balancing is easy for the busy GM
- All of the classes are good, there aren't any trap classes
- Teamwork is highly encouraged through class and ability design
- Degrees of success/failure
- Easy, free access to the rules
- The ORC license
- https://pathbuilder2e.com/
- Pathfinder Society Organized play is very well done and well supported by Paizo
- Women wear reasonable armor
- The rune system for magic weapons/armor
- And so many more
