So even in the sense of box office power and popularity, the two are not in the same universe.
Yes... starting with Iron Man he has had many 100 million grossers. That is the point of comparison, Downey entering that franchise (43 at release) when he did and Affleck entering this franchise (42 at release). Before Iron Man, Downey Jr. had exactly zero 100 million dollar grossers. Before this Man of Steel sequel, Affleck will have had at least 7, including Daredevil, which made more than twice its budget worldwide.
Buzz (good or bad) is not necessarily box office, but Affleck's casting has generated more buzz than any other casting in recent memory.
