I have to say Gwen. Gwen is a mysterious character that has mais personality than Courtney. In my opinion, Courtney is an annoying character and she is way too bossy in TDA. She has to call her lawyers because things do not go her way. Gwen is way better.
Courtney not that boyfriend thief Gwen (why did she steal Duncan why) Although Courtney gets fooled por Al she still wanted to get back at Duncan and Duncan made Gwen (fake) cry to get Courtney out but in the end Gwen lost
Of course Gwen is a lot better she's a whole lot mais popular and she's a fã favorito who in the world would like Courtney she's bossy mean and cares mais about winning the competition than anybody else and that's what screws her up she has no one plus a lot of people have a crush on Gwen, she's mais of the protagonist of the whole show.
