let's break this down size wise.
big/medium bands: McGavok, DB, LaVergne, Father Ryan
small bands: Adamsville, East Robertson, Oliver Springs
also, are we going to compare difficulty or just excitement?
excitment, it is hard to compare with the show style bands like Austin East, (Like drumlines in the movie drumline).
if we are talking difficulty, then groups like LaVergne and McGavok(big/med bands) usually play some really hard stuff. McGavok almost always has a really strong snare line. in small schools I have heard OS play, and they really play some stuff. and when you talk about a really small school that is pretty amazing. also, every year they seem to really have some crazy tenor stuff going on. i would rather watch a line play some really hard stuff, and be clean, than see a line play easy stock arrangements and not be challenged and be really clean.
but hey, that is why we all have our opinions.
