the issue here is that "poverty" vodka can mean anything, from decent if not great tasting stuff good for mixers, to poisonous paint stripper.
take for example whiskey - you can't have good poverty whiskey, because both 1) its made with stuff which costs more than potatoes and 2) it needs aging, but you can have pretty decent poverty gin, vodka, and a whole bunch of "made with weird stuff" liquor, like cachassa, or sambuca.
personally, i dont like vodka which tastes the way it should, so, no smirnoff for me. otoh Absolut, Zubrovka, and all those other "infused/flavoured" vodka, i'll drink them happily, provided they are thickened with cold.
(still, it's my 3rd choice if not 4th)
