3Stan Marsh
South Park is definitely not a show for kids and picking the favorite character can be difficult because they are simply all cool. This time, we will go with Stan Marsh, who is the most sensible one out of his friends. Stan had trouble reconciling his good demeanor with the cruel world around him, so he has become depressed over the course of the series. Stan dad is a cool character as well, while Stan himself is a hit with the girls. (If you say Cartman is the coolest, we will not argue. Or Kenny.)
