Susie
She never lets Angelica get away with her lies like telling the babies that her dad is digging for pennies and she needs all the dimes from the sale of their lemonade. (Her dad was pulling weeds.)
She is very athletic and loves to go to Day Camp (unlike Angelica). She is also a good ballet dancer (Angelica could use some help in that field) and unlike Angelica she always shares her toys.
