I'm sure the TRR is a cool route, but I don't care for the Rocky Mountains. I have travelled all over the world and no where, in my opinion, holds a candle to the beauty of Vermont, NY, NH, MA and Maine.
True to Vermont I like green mountains. I don't like rocky mountains that are bare, less colorful, and all exposed. The West/Southwest doesn't impress me. I'll take Glastenbury Mountain, Hurricane, Wittenberg, Moosilauke, Old Speck, etc.. etc.. etc.. any day over anything in the Rockies or Southwest that I've witnessed. The lushness of the peaks out here is much more beautiful, and the mystique as to what's within the forest cover is more appealing to me. The Kancamagus is such a mind-blowingly beautiful route, as is Route 125 in the Breadloaf area of Vermont.
