Which ko victory was more spectacular?

[Pastrano]

Comparing 2 splendid Argentinians and their stunning ko victories over more or less celebrated American fighters: Jorge Fernando Castro's ko over John David Jackson and Sergio Martinez's ko over Paul Williams, which one is more spectacular? I have a hard time choosing, but I think Castro's was, since it was a come from behind ko and really nobody could have predicted or expected it. He was getting a beating and suddenly just laid the man out.
