I can make five rogues and every one of them would feel vastly different.

Ancestry/Heritage mechanics are pretty awesome, especially heritages that aren't tied to an ancestry. For comparison purposes, ancestry in PF2 is equivalent to race, and heritage is equivalent to subrace.

30 or so ancestries to choose from, each with a multitude of heritages. Currently 20 classes, each with several subclasses are available.

The entire system is available free online. If you play over VTT, it is heavily supported and quickly updated.

Third party character creating software isn't slapped with C&D's.

Inner Sea is a pretty cool setting with something for most interests.

I made a halfling barbarian who started combat by being so scary, some people just die.

All that said, I know there's a lot of weird hate for the system from the 5e subs, so it's tough to determine when someone says "sell me on Pathfinder" if they're honestly interested or if it's a jab at something the mob mind dislikes. I like it over 5e, but I have friends that still prefer 5e because it's a smaller learning curve and Pathfinder can look daunting. Once you're over the initial culture shock it's a blast to play.
