My personal favorite was Q48 @ WPI:

We went in with a lot of confidence because of a match replay due to a missed crossing where we would have won otherwise. Besides that, 4048 and 3623 were great teams to work with.
As for our best, F1 @ Boston:

We were lucky enough to get drafted onto a strong alliance, and we got to show our defensive skills, preventing a tower capture.
