Not really, if that was the case then Batman would be higher.  I like Iron Man more because I see him as being more human.  He deals with vices and is very flawed, often fighting criticism with sarcasm and narcissism.  

He has reasons for his actions, he has guilt, he knows loss, and he deals with them in a relatable, albeit destructive manner.  It is these reasons that drive him to better himself through his Iron Man persona, but that comes at a cost.

Iron Man’s a character of give and take, of failure and of success.  He’s a man in a metal suit, but he’s still a man, and that’s why I like him.
