I totally understand, Persona can be a bit of a drag with all the dialogue and stuff so starting over can be a pain. Yeah I would recommend Royal purely off of the extra content (two new characters) and the little gameplay extras they've added are nice. I liked both, they changed some boss battles in Royal though. If you end up liking (or disliking) the game you should check out the Shin Megami Tensei franchise as well. Same company, almost identical gameplay mechanics, but darker themes and a bit more 'mature'.
