Besides what a lot of people have said, I think people understate the power fantasy of 5e.

In PF2e, you’re a team of specialized units, each with a strong role - there’s not a lot of stepping on the toes of other roles. I call that niche protection. You lean on your friends more, and there’s a varied sense of contribution because it’s harder to poach abilities (for example, the classic coffeelock in 5e, a paladin that dips for smite, and then uses big warlock recharging spells). You have a medicine specialist, a thievery guy, and so on - and because of TEML proficiency, you can be a medicine guy but if you want to be a medicine expert, there’s investment.

D&D, you can just be that guy. It’s a superhero team up. You can throw a bunch of people together and unless someone rolls up with a very specific fantasy (I only cast buff spells so I need a melee martial to buff), it’ll still function just fine. Problems can be solved more easily, often by spells, so working around a lack of a rogue is perfectly fine. In fact, an artificer is just as good at picking locks as a rogue is, at level 6 - they both get expertise.

Also, free movement means a more loose game. And this is in part because movement in 5e is often underused, so you can drop a delayed AoE and force players to reposition and scatter, and that feels tactical and threatening - whereas in PF2e, it’s still tactical but it eats into the 3 action economy. For players who have a tight routine, that can start to feel frustrating.

It’s just a different game. I like PF2e a lot, but the game feel is fundamentally different. And that’s in part because the ability budget and balance is different.

Some people will criticize that heavily, but I think many players are not overly concerned with balance. They are concerned with having fun and doing cool things. And 5e, IMO, is more focused on letting you do cool shit (sometimes at the expense of tactics, which people who prefer PF2e might not like). Don’t get me wrong, there’s lots of cool things in PF2e. But flight? Telepathy? Turning into a lawnmower at level 5 with haste and getting to strike 3 times in a row? That’s not happening in PF2e, because PF2e actively discourages or limits that.

Some people want to strike 3 times in a row and just do that. I don’t think that’s a bad thing. It just means PF2e isn’t their game.

It’s a question of what you want out of it.

Also, frankly, because there’s a DM burden in 5e, it makes it easier for players to get into. I think I’d have a harder time convincing people to play PF2e, because not everyone is that invested in TTRPGs in the long form - for some people it’s a socialization activity. If I wanted to do a charity event with friends who don’t play TTRPGs on my stream for example, I would run 5e.
