For me AA Joker is probably my favorite, yet to receive Purple coat yet, though. Not sure if it's the clothing, the paint app, the posture of his neck, or a combination but there's something about it much more intense and different than the Tuxedo version for me, I think it's great for being a sideshow exclusive, especially compared to what's being offered this year!
Also no surprise this wasn't released - if people think AA is basically an accessory pack this too would be considered as it's the same sculpt and just different clothes.
