I must agree with Icehog3 to each his own!
Grey Goose, Opulent, 3 Olive, Ketel One, and so on are all designer Vodkas. That's not to say that they're bad, hell no, in fact Ketel One is one of my top favs, but they are creations of the modern age.
For a true classic, time honored Vodka it's hard to beat Stolichnaya Gold or even the standard version! I love the gold!
