I don't know why a lot of people don't like the Silver Centurion armor. For me, it looked great and the additional abilities (like the Stealth Mode) were awesome. Plus, I think the silver and red color scheme went together better than the gold and red. It was also the first time that Tony Stark would change his armor on a more frequent basis. The armor that preceded this was Iron Man's standard look for over a decade, except for the time that it grew a nose.
