I have finally found a vodka I like.

I tend to drink Vodka straight on the rocks. That requires a very clean tasting vodka. My favorite in that regard is Belvedere. Many of the others -- even the esteemed Grey Goose -- have an unpleasant harshness and aftertaste.
Hanger One is OK too, as is Chopin. Ketel One is a good vodka, but is better for mixing.

Yeah, just my opinion. Drink what you like.
