We have seen most of te cirque shows, Alegria (twice), La Nouba (countless times), Quidam (Three times), O (once) Mystere(once), Dralion (Once) and Varekai (three times)...
I enjoy all Cirque shows as they all have elements that make them different from the others. For me personally Mystere (in Las Vegas is my favorite) but La Nouba is just as enjoyable. I was mesmerized by the effort and the thought that went into O (the water one in Vegas) but was not as impressed with the acts. In my opinion it is a bit more impressive to have to land on someones hands or a tight wire or just a stage than it is to land in a pool of water. Don't get me wrong, O was worth every penny and I would go see it again, but it was not my favorite. I enjoy La Nouba a lot as the music is very playful and the story is fun. The performers put so much into any Cirque show that I admire them all.
