Giants fans, which was the greatest Superbowl win XX1, XXV, or XLII?

XLII was probably the best obviously because we beat an undefeated team, maybe if not one of the best teams in NFL history as a fifth seed wild-card as huge underdogs. XXV was the most exciting with Norwood missing the 47 yard field goal with seconds left on the clock. But the Giants and Bills both finished that season with 13-3 records and first in their divisions, so it wasnt suprising that they won. Superbowl XXI was exciting in the first half but the Giants blew them out in a convincing 39-20 win.
