This site pretty much says it all.
My preference would be Bishop; larger and more options (plus the Mountain Light Gallery for Galen Rowell fans and also Schat's Bakery).
Another thought, after reading your starting point....
SF to Reno to Bishop is too long for a day's drive (425 miles or so). If you want to make Bishop, I would take US50 from Sacramento over Echo Summit through South Lake Tahoe, connecting to 395 someplace south of Carson City (near Gardnerville).
Even that will be a long day (360+ miles), so maybe Bridgeport is a better bet. The US50-SLT-Gardnerville routing is around 275 miles, and considering some of it is mountain driving would make for a full day.
