Perhaps another perspective on the question: Is it the apparent magnitude of the sacrifice that matters, or the motivation behind the sacrifice?
If the first, then how would we measure that magnitude? By the stature of the person? The number of people impacted? In that case, if we accept the Biblical portrayal of who Jesus was and what his ransom accomplished for all mankind, then his sacrifice would be the greatest possible.
OTOH, if motivation is the key factor, then the examples you cite are all equally as great as Jesus' sacrifice. Indeed, in that case, someone who gave up their life merely out of a feeling of obligation (perhaps, like a soldier who took point only because he knew he would be fragged if he didn't), and not because of true love for their fellows, would earn recognition, perhaps, but probably not honor.
IMHO, I don't think that the Biblical Jesus would consider his death to be greater than anyone else's.

edit to add: Jo 15:13 "Greater love has no man than this, that he lay down his life for his friends." Pretty much levels out the field, eh?
