How does stream/river fishing in the smokies compare to the Rockies?

[HuskerFlyFisher]

We live 4-5 hours from the nm and Southern co Rockies, but I've mainly fished the smokies since I have two cabins there. I would like to hear from David knapp and others as to how the fishing in the locations compares - how productive the fishing is, sizes, differences, and similarities.

My dad claims that the Rockies are generally much more productive and that the fish are bigger.
