I only played Persona 5 Royal, finished it a few weeks ago actually, but I'm quite mixed about it.
Art direction is great, gameplay is better than your usual turn based jrpg (but I wish it went even further with more strategy and less repetitive combats), story was okay, but...
I found the pacing absolutely terrible.
It talks SO MUCH, for nothing. It's so long. I'm not against long games, I loved Baldur's Gate 3 and my 220 hours on it, but it took me almost as long to finish Persona 5 royal while it really didn't feel like such a memorable journey. It felt like all this could fit in a much shorter game.
I also had a big problem with the lack of freedom. I'm not sure how to explain it, but even very late in the game, it often still felt like I was in a tutorial somehow. Too much hand holding, quite often you can't do what you want because Morgana decided it wasn't the right day to do that etc, it's a very weird feeling. It's an extremely linear game that tries to make you think it's open.
It's still an overall good game, otherwise I wouldn't have finished it, but I think it does have issues. A better pacing would really help. Oh and, actual "cutscenes", with camera movements etc... like in most other games, instead of just a visual novel style presentation, because this didn't help with the overall rhythm either.
Maybe something that didn't help is also that I played Midnight Suns before Persona, which is actually a much better "Persona" game in my opinion.
All the confidants, perks etc inspired by Persona are actually much better used, with a better freedom feeling and more strategy, in Midnight Suns (which in my opinion is the game with the best turn based combats I ever played).
I know people don't like the social aspect in Midnight Suns, but this is confusing to me because I found Persona 5 extremely worse at that.
I don't think I'll play another Persona if they're all like this, except Strikers which I already own and plan to play, but it's a shorter game.
