Voted for Poison (original, vintage,heavy bottle and dark liquid of course), the reformulation is not too bad i think but i still prefer the original.
Coming close on second is the androginy of Midnight Poison, not just because of what it is but because the scent itself is very attractive to me and it goes well with my skin and yes, of all the Poisons i feel the most comfortable wearing it, since basically this could've been a conventional "man's scent".
Tendre Poison should not even be called a Poison, it just never was a true contender for the line. I would've been happier of the scent came to the light of day as something other than a Poison, since the scent is really not bad at all. Somehow i call it "Green nightingale".
