Couldn't pick, they all have their unique qualities. Each member is extremely talented and they are humble and personable people. LaBrie is a great singer and a sound guy, Petrucci is an amazing guitarist and is really humble and down to earth, Rudess is an affable, gregarious guy with an infectiously fun personality, Mangini seems like, and I believe he will prove to be, a really modest and easy-going person with likeable characteristics and Myung is an outstandingly skilled musician with the most nimble fingers I've seen in a bass player, and, although the more reserved member of DT, is nonetheless a nice guy. A great band filled with great people...did I miss anyone out?!!
