DS Daily: What could be manlier, Contra 4 or Metal Slug 7?

We know Metal Slug 7 hasn't released yet (we're counting the days!), but the latest trailer for the title proved one thing to us: this game is going to be one manly time. But, what to do, as Contra 4 already takes up space on our shelf of manly stuff?

Are we to take it down for Metal Slug 7? Can the two co-exists as incredibly awesome and manly games? Which one do you think is more manly and buff?
