No matter how exciting, difficult and challenging a singleplayer game can be, they can never offer the same challenges that co-op games have. No matter how good you are, you won't win in a co-op game if you cannot cooperate with your teammate.

Having a friend behind your back to play with is the best

Other than that, anything is better when you are doing it with your friends. Co-op games allow you to slay evils and explore the world side by side with your buddy or just simply have fun and beat the shit out of each other.
