One went off the backboard from behind. The other went back in time and over a former champ. Both got everyone out of their seats. Both were spectacular.

But which one was more spectacular than the other?

Tough choice? We thought so. And that's why we're asking which perfect dunk did you like better:

Allen Iverson to Andre Iguodala off the back of the backboard or Nate Robinson skying over the 1986 dunk champ, Spud Webb.

Spy the video below (you'll be glad you did) and then choose which vision of perfection you prefer.

Watch the video: Which 50?

50: Nate Over Spud

50: A.I. to A.I. Off the Glass
