Three reasons I am mad about 3:
1. Flavor: clean but not without character.
2. Hangover: my pal at Wally's Wine and Spirits claims you can drink as much as you want and not get half the hangover you get with other vodkas. And he'd know (man, I want his job).
3. Sporty-ness: There are really two aspects to the picaresque nature of 3. On one hand, it's basically a sports drink, it has no sugars and is gluten-free (and, oddly enough, vegetarian?!), and i would totally hydrate with a 3 rocks. On the other, how badly do you want to clip the top to a climbing harness and hit the crag? I have a friend who says there's a window after drinking a redbull and two shots of espresso when a human can climb pretty much anything... add a shot of 3 and I think it'd be safe to remove the "pretty much" from that statement.

...Also, they have it at our corner store for $2 LESS than Stoli... Chin up, my smooth Russian pal, you know how the saying goes, "one is silver and the other's gold."

I was skeptical about how 3 would taste at first, but that is all a thing of the past. It is now one of my favorite premium vodkas now, and affordable at that. The main thing that made me skeptical about 3's potential flavor, is that it's distilled from soy. Vodka is produced from grain, potatoes, molasses, beets, and a variety of other plants, but generally not soy. Soy has become so popular as a foodstuff over the past several years, however, that it was bound to happen eventually. Anyway, because 3 is distilled from soy it is: carb-free, gluten-free, and sugar-free! Those were my other reasons for trying it. It has the mostly "neutral" flavor that one looks for in a vodka. So, it works well in cocktails, general infusions, etc. One stand out characteristic, however is a slight "sweetness", which makes gives 3 its own character. I highly recommend this one.
