Vert is beautiful, an absolutely unique green and the "must have" of their collection IMHO... Shotgun's another fave of mine, a beautiful shimmery rose/taupe neutral colour.
None of the other ten or so other colours I've had that are currently in their range I would particularly recommend over MAC stuff....
But, d/c ones I like and would recommend if you see them somewhere, grab 'em:
-Pallor is the most beautiful metallic duochrome purple e/s (it's similar to Parfait Amour but ten times easier to apply, and a lot sheenier/more metallic)
-Rust is a medium apricot orange colour with a stunning green-gold duochrome through it, very pretty and quite unique
*grins* I recently got the opportunity to buy up a whole pile of unused UD "tester" pots for £1 a shot, many of VERY old colours, wasn't I a happy lass
