Semantics. They are the same. They're all (supposedly) 1/6 scaled action figures based on licensed Movie/TV characters.
I don't know why you Medi apologists have to get so defensive every single time the issue is broached. You're as bad as the haters or even the Sideshow apologists on here.
I own a dozen or more Medicom figures. I've always felt they were a bit over-priced, but it's now reached critical mass for two reasons: 1. Their prices have gotten even more puzzlingly high, and 2. Hot Toys (and even Sideshow) have really raised the bar in quality and detail while Medicom has not. I recently got the Hot Toys TDK Batman and Joker figures for $140-150 each as well as the Medicom RAH Henry Jones, Sr for $150. And, sorry, I can't help but shake my head at the fact that these figures are all roughly the same price.
If your contention is that Medicom makes non-detailed, cartoonish toys instead of mega-detailed 1/6 scaled action figures and that's how Medicom purists like it, then that's all well and good. Seriously, that's fine. But let's also stop pretending that these are "high-end" items. Because the bar has been raised, and they're not anymore. The only thing high-end about Medicom 12" figures these days... is the price.
