Maybe it's the fact that it doesn't have "Contra" in its title...
If I'm remembering what the Contra 4 museum had to say about that, I believe "Contra" was left out of the name to avoid a reference to the Iran-Contra conflict or something (excuse my ignorance of history). The original arcade game is still called "Super Contra", and considering the original Contra was such a hit, just about everyone would know what the stylized C stood for anyway...
Back in the NES days, before I became such a Nintendo fanboy, my meager game collection was actually not mostly Nintendo-developed games. Though considering I hadn't heard of the arcade game Contra, and I didn't play it at a friend's or anything, I don't know what compelled us to buy the NES version...but I certainly don't regret it. So comparing Contra and Super C, Contra certainly wins with nostalgia on its side, though I do remember a good time of playing Super C at my brother's friend's house, and they had what seemed like a really big TV at the time.
