There're pretty large error bars on these, but preliminary rankings:
Aradia > Terezi > Nepeta > Karkat > Kanaya > Tavros > Feferi > Sollux > Equius > Vriska > Gamzee > Eridan
Equius would probably be higher if the most recent scene he was in involved him being a mega-creeper. Error bars especially high on Feferi and Eridan, haven't read much about them yet.
