I'd be okay dating either of them, but I guess I'd choose an extrovert if I had to pick. I've mostly crushed on extroverts, I guess it's that whole opposites attract thingy, I just feel like it would be easier with an extrovert.
I would say it would be really cool to be friends with a guy whose a combo of the two. Like where he didn't really like talking to most, but has like a small, really close knitted group of friends. so basically like an introvert to most people, but a extrovert to his friends.
