I've tasted Shasta Gold and Yosemite Gold, from a store, and in my personal opinion, I definitely prefer Shasta of the two. It has a very orange-like flavor, but with a nice sourness, deeper level of flavor, and very aromatic.
I'm pretty sure they had Tahoe Gold one time at that store, which I tasted, but to be honest I might be misremembering and can't be completely sure.
If I did taste it, Shasta Gold was definitely the best of the three.
In case anyone was wondering, this store happens to carry very obscure varieties, so I've gotten the opportunity to taste all sorts of weird varieties there. Some of the varieties are so obscure/unusual I can barely believe they are being sold there.
I was a huge huge fan of Shasta Gold. It was almost as good as the best Satsuma mandarins I have tasted, although it's hard to compare because it's a different type of flavor. (I would say they are not in the same mandarin family when it comes to type of flavor)
