They do match up pretty closely but I bought the antidote version and it just has this extra synthetic touch that ruins the experience for me. They concentrate (pardon the pun) on ramping up the strength and use it as a selling point "all our perfumes are eau de parfum strength" but I think it's to the detriment of quality.
I realized after a few wears that I couldn't be satisfied with it knowing it's not quite right.
Btw you're taking about the Australian company, yeah? They have an outlet near me, but most on this board wouldn't have heard of them, let alone smelled to compare. I've been meaning to go back though as it's been a while and my nose is probably a little better now.
