I prefer to travel west-bound over Sonora (mostly because of the dramatic sights seen when reaching the pass from the eastern side in early spring.)
Ebbetts -- Most certainly -- east bound -- Make sure you find a place to stop at the last lake before the pass. There is a cabin on a little island in the middle of the lake that is magical.
Tioga, I've gone both ways, but maybe west-bound is more thrilling.
Monitor Pass -- You gotta go eastbound -- that drop to the desert is thrilling.
For that matter Sherman Pass is pretty dang cool -- and again eastbound and the descent to the desert is memorable.
