Who's your 'Best Girl'? Are Tsundere really the best girls in anime?

Joey The Anime Man and AkiDearest talk about their Best Girls. Joey says you're allowed more then one; you can have multiple 2D girls in your life. His Best Girls are often ones who are cute but powerful and confident. He likes anime girls who have many hidden sides. Aki has multiple Best Girls, one being Haruko from Fooly Cooly. A lot of people like Tsundere; characters who are cold or hostile at first and then show a warmer side over time. The duo aren't sure they agree. Who's your Best Girl?
