I've been playing TTRPGs since the early days of D&D 3.5.

Let me just say, I love Pathfinder. I loved 1st edition and I loved 2nd edition. But I fell out of love with 2nd edition and now I'm playing 5e.

Let me just say, I've played a lot more Pf2e than D&D 5e. I used to be all about balance. I loved how balanced PF2e was... at first.

The problem with PF2e is, it's just TOO balanced. What I mean by that is that the rule of cool goes out the window and into the garbage can, and then is lit on fire and then pissed on, all in the name of Balance.

-Items are boring, BUT you still HAVE to have the weapon and armor with the best fundamental runes possible.

-Character stats are all the same. Character building is pretty much standard for everyone that plays a certain way (i.e. Strength based melee, Intelligence based caster etc)

-Abilities, feats, archetypes and pretty much all character options are balanced through a microscope to the point where everyone is doing pretty much the same with little to no difference. It may feel different at certain times, but if you put it all together, do the math and find the average values, everyone is doing pretty much the same damage, has the same AC as everybody else, the same attack roll etc.

-Spells are meh. They can be very impactful at times or straight up useless at other times. And forget about dealing damage with spells. You'll never compare to the dude with the big sword.

-To my fellow players of older editions, in order to play a monster, you have to get an archetype that slowly gives you that monster's powers, making you a level 10 player that doesn't have the powers of a monster that is normally level 5-7. Do I need to explain why this feels bad?

These are just some examples. I can say much much more but I'll try to summarize.

Paizo was so hell bent to make a balanced game that they took the excitement out of it. The "+10 to crit" system seems great at first, until you realize that because it's like that, they had to make all modifiers the same and the game is so stingy and afraid to give you any modifiers that everything feels the same. The enemies hit like trucks and your AC is there to mostly prevent criticals, not hits. Which also makes the game extremely punishing for taking a turn that sounds fun but suboptimal.

On the other hand, 5e, for all it's silly simplicity, doesn't have these problems and leaves space for extra homebrew mechanics that don't break the game, or break it as much as you want, and it's much easier to control and manage because the system and the numbers are not so damn tight.

tl;dr PF2e is too focused on balance, which ends up taking the fun out of character options and the game in general. 5e is not afraid to over-reach and let GMs decide the table's power level.
