What kind of similarities does susie syncra has with emily elizabeth besides heelward and clifford?

besides cliff & heel? their fahsion style (longsleeved collared shirt, mini skirt, striped socks), the fact that they used to live in an apartment before moving to an island. and their kindheartedness towards people in general, i guess? oh and them being moralistic, optimistic & athletic (not sure about this one cuz i dont know how sporty suzie syncra is).
But i guess suzie syncra is crazier a bit, whaddaya expect, it's supposed to be a parody, pardon the obvious similarities.
