Who's the smartest?

Iron Man/Tony Stark, Batman/Bruce Wayne, Beast/Hank McCoy, Blue Beetle/Ted Kord, Black Panther/T'Challa, Giant-Man/Hank Pym, Mr. Fantastic/Reed Richards, Ozymandias/Adrian Veidt or Dr. Bruce Banner/Hulk. Which one is the smartest and why?

I don't see Reed Richards being below anyone else on that list.

Reed Richards for sure.

Reed.

Reed & Pym.
