>>7494962PotP is a garbage line. Best figure is Slash. The rest can go right in the fucking bin. If you can tolerate combiners, I've heard Abominus is cool, but even then, most of the Terrorcons that make him up are a bit shite.
Punch/Counterpunch was an online exclusive and was basically a PotP release in name only. He's definitely better than the rest of the line in terms of looks and plastic quality, but I still wouldn't pay much more than 20 bucks.
