Konami made Contra, right? Contra's the greatest series ever, right? (You could argue, but you'd be wrong) Therefore, buy logic, Konami is the greatest ever. Contra, Castlevania, the TMNT arcade games, The Simpsons Arcade, X-Men Arcade; I think I'm stuck in the early 90's, but Konami is awesome.
Capcom did make Street Fighter and Megaman, two more of my favorites, but they don't compare.
Besides, who ever heard of the Capcom Code?
