Stinkor and it's not even close. Nothing else compares. Probably because I'm Blinded by Nostalgia™ and I have great memories of Stinkor, his colors, and his scent.
I hate NA, but Slush Head is amazingly done! He's probably 2nd.
Temple of Darkness Sorceress is the best repaint in teh lien so far so she's up there as well!
The Griffin and the Mighty Spector are both a bit "meh" to me.
