The Bluecoats of course! I am biased but doing my best to look at the two shows objectively I felt that the Bluecoats should have been 1.5-2 points ahead, heck, even the SCV fan next to me felt the same way. Bluecoats music really grabbed me and pulled me in which surprised me because I thought a boxing theme would be cheesy. I am glad they proved me wrong. SCV's music while very good, and I enjoyed the show, just didn't hit me on an emotional level. SCV had better designed drill overall but both corps had the same level of dirtyness in their drill. I really feel that Bluecoats had a superior show.
Also, you can tell from the posts that many, certainly not all, voted for SCV out of nostalgia as if to say, "they're SCV, so they should win."
