I am not asking for a list of shojo's w/ guys as main characters, I know that there have been many posts like that, and I am also not interested in shojos with female main characters, I am specifically asking for manga's with guys as the main character.
What I want to know is:

Which manga's w/ male leads have you read, or which one has been your favorite and why?

I think my favorite manga w/ a guy as the lead is Natsume's Book of Friends.
I am really enjoying that story right now. It is so calm, and I like the fact that it focuses on friendships more than on romance for the main character.
But overall I think I've enjoyed most mangas I've read with male leads, even though some of them have annoyed me at times.

Other's I've enjoyed have been:
Game x Rush and NG Life
RG Veda
Phantom Dream
Tokyo Babylon

Do you find yourself sometimes enjoying a shojo w/ a guy in the lead than if it was a girl?
