I voted for AmCab, even though I'm so new to BD I'm not even sure I have a "legitimate" opinion.
I have never seen BD live, only through the videos linked here and on YouTube, but, if pressed to explain my preference, I believe I see AmCab as exhibiting ...more life, or maybe more energy, through the breakdown/isolation of the BD moves. Egyptian dance seems to blend all the moves together, where AmCab both blends them and then isolates them, which makes the dance more fun (at least, for me).
This is just an observation from a total tyro, and I hope I make sense (and don't offend anyone!).
