El Charro might have won here simply because it offers so many varieties! Besides the standard margarita, with our old friend Jose Cuervo and fresh citrus, El Charro makes plenty of variations. You can get 'em with fruity flavors like strawberry, peach or mango; you can get 'em made with prickly pear nectar and Herradura silver; and if you're feeling especially flush, you can get the '42 Caddy, which features Don Julio 1942, Grand Marnier and fresh citrus, all of which will only set you back $25.
