i have to say batman, i am not that big of a DC fan either, but i always prefer him over iron man. he is a more rounded character, and his stories are, in my opinion, better written and depicted. the art style is also grittier and darker than those of iron man. the characters themselves also differ, batman is charismatic and by far the kinder of the two while tony stark is kind of a jerk and very stuck up. ive never been a fan of the avenger series despite my marvel fan base, but i will always pick up a new batman
