There are ways to keep a Persona viable long-term

Persona games are typically scaled for you to be fusing and creating new Persona throughout, so it’s uncommon for most players to be using creatures they had at the beginning of the game by the time they reach the end. However, if you find yourself attached to a specific one early on, there are ways to keep them usable throughout the game. I tend to gravitate towards the main character’s first Persona, like Orpheus in Persona 3. To keep him in my roster, I use skill cards to give him new abilities, which keeps him versatile, so I don’t have to switch off him that often. This means he doesn’t miss out on experience points and remains viable throughout the whole game.
