US 64 is a great scenic drive. From Cimarron it is a little slow and twisty up to Eagles Nest following the river, but is a good road. The next twisty, slow part is from Angle Fire down to Taos but again a good scenic road. From Taos to Tres Pedres it is relatively flat and mostly straight. From Tres Pedres to Chama it is a great scenic drive with long curves and some straight driving through valleys and over ridges. From Chama over to Shiprock it gets into dryer high desert mesa lands and follows valleys through the reservations. Still a good road. There are some open range areas on the reservations so watch for cattle, horses, goats, etc. and slow vehicles on blind curves and dips.
