Most Helpful Guy
Certain movies, music types, video games, general topics. My bestie is a gamer nerd like me and I can talk like I wish since I know he knows what I mean whereas my girlfriend would listen but won't know what I'm even talking about. Some movies even my bestie and I love the home alone movies by girlfriend just doesn't.

I don't have a best friend, but for example playing games or sports with my family is more fun that with my boyfriend, because he is really competitive and always takes every competition very seriously.
