I have to say Gwen. Gwen is a mysterious character that has Mehr 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 Von 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 Mehr beliebt and she's a Fan Favorit who in the world would like Courtney she's bossy mean and cares Mehr 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 Mehr of the protagonist of the whole show.
