I really like the Aboslute flavored vodkas. I mainly drink Absolute Raspberri and soda....that's almost a "diet" drink since it has only 70 calories - but they go down pretty fast! I like it because they've kept the Raspberri slightly bitter. Of the ones I've tried with soda, my preference is: Raspberri, Peach, Vanilla, Mandarin, Pear.... I haven't had the opportunity to try others, they aren't stocked so often in Thailand bars. You'd think Mango...but no.
I will say that I don't care mcuh for the Smirnoff flavors I've tried. The raspberry is way too sweet and the cranberry is okay, but a splash of cranberry in the soda and straight vodka is better. Ironically, I think I prefer the non-flavored Smirnoff to Absolute, but for the flavors it's no contest.
