Not the same to me. P3 had a better atmosphere and more tension than P4 but it's character writing was a lot worse. In P3 every high-schooler acts like they're 35 except for Junpei, and everyone is Batman with dead parents. They were still likable and the cast was pretty good but P4 did a much better job writing its characters and making them have personalities.

Black Turtle did a pretty good job.
