Ciroc is and will not be available in Canada due to labelling issues because Ciroc is distilled from Grapes so by the retarded Canadian Liquor Laws, it should be labelled a brandy whereas Ciroc is like "da fuq?" so they just rather pull all their shit back to the States... but I agree Ciroc is very smooth chilled, the Red Berry flavour is especially nice. I try to grab a bottle everytime I'm down south.
Anyways, I picked up a bottle of Russian Standard Platinum at Duty Free last time and it's pretty darn good too.
Skull Vodka tastes like ass, especially for the price point, hundreds of better Vodka's out there for half the price. Uluvka is another expensive vodka in a fancy bottle that tastes like unicorn piss.
Belvedere > Goose: Goose is for posers, after drinking the REALLY good shit, Goose tastes like rubbing alcohol. Belverdere actually tastes better.
Stolichnaya > Smirnoff: Stoli is really good for the price. Smirnoff is the basic standard, wouldn't ask for or buy it personally but if it got served mixed in a drink, wouldn't mind it.
Absolut > Potters: Both are disgusting, but if I had to drink shitty fire water I would take Abs over Pots)
Van Gogh makes a delicious Espresso Vodka, but the Double Espresso is way too syrupy and thick for me.
SKYY is meh.
Ketel One is above average.
Yeah I went through quite a vodka phase a while back ... actually still am lol ...
I recently imported some Ultra-smooth, premium vodka that's (as far as I know) only available in Vancouver (maybe even Canada, maybe even North America lol) at Ebisu. Drop by and ask for a shot 
You won't regret it!
