Your skill choices and party setup are FAR more important than any single level. Especially in Persona 3 where there are bosses that can become completely lopsided against you with the wrong party member, skill, weakness, etc.
Case in point: Look at how easily you can cheese the very first Tartarus boss by simply using a bow on your protagonist. While it never gets that easy again, it's just proof of how the game is designed.
