The metal slug games have a awesome art style, and trends more towards comedy (morden's scream and "come on boy!" will never make me not laugh). Contras can have a harder hitting faster-paced playstyle, and the boss gauntlet contras like contra hard corps and hard corps uprising has action and a soundtrack that keeps slapping you in the face.
I like my favorite contra game (hard corps uprising on the 360/PS3) more than my favorite metal slugs (Metal slug X and 3).
Once you get in the zone to these kind of soundtracks its hard not being a huge fan of the playstyle, lol:
