Grey Goose is good as far as vodka goes, but it's mainly just slick marketing. The reason no one knows it in France is because that's all a scam. It's an American company that wanted their brand be French for image reasons. Something like Sobieski is under half the price and maybe only marginally worse. Unlike whisky, I don't think it's ever worth splurging on vodka.
