I think that having the finale at 12,000 feet was a huge disadvantage to all chefs. If you want someone to cook them the best meal of your life putting them at a cooking disadvantage is not the way to do it.
I was surprised how poorly Casey did, Dale blew it on one dish and Hung made good dishes. Overall Hung did the best in the finale, Dale was close. Casey will continue to learn, Dale will only get better and hopefully Hung will put some soul into his food. He has the best skills, Casey has the most heart and Dale found himself.
