I too believe the Blue Devils won because they had a better show overall. However, I thought there were more entertaining shows down the ranks. Again, though, it's just a matter of opinion. I have heard people talk about how boring the Blue Devils show this year was, and others claim it was one of the best in DCI history -- proof that what is spectacular to one person, isn't necessarily to another.
Now, I'm not saying the Blue Devils never put on an entertaining show, but too me (just my opinion) it's like this, there are one or two hot charts they WOW me, and the rest of the show is fast-forwarding through. That said, I loved their drum book this year -- the writing was outstanding, and they performed the hell out of it. I think they're a classy organization, and are very good at what they do. After all, they wouldn't have won 12 championships if that wasn't the case.
As for '93 Star, I have found it to be like this, either people love it, or generally just don't care for it at all. There aren't very many people I have come across that are in between the two. I'm not even sure I'd even classify it as the greatest DCI show of all time, like some have done; although, as a corp, finals night was our best performance...everything just finally seemed to click in to place. I'm also not saying it was a memorable show by any means, even some of us who marched didn't quite get it until Finals week. However, from a marching/performance standpoint, it was very memorable season.
