I don't know which has the best dialogue, but I can tell you which personality type has the worst dialogue - jocks. All they ever talk about is muscles and fitness. It drives me insane. Talk about something else for a change! Maybe I'm just not a fan of "gym bros" so to speak, because I myself certainly can't relate to the dialogue since I can barely work out due to health conditions. I think the type I relate to most is normals or peppies, because I certainly wouldn't mind being a rock star (instead of a pop star)!
