Are those other brands movie based Iron Men or comic versions? I just want one good classic Iron Man to go in a display of classic main Marvel characters!
Sentinel's are all, with the exception of one exclusive, based on comic armours. I don't own anything by Comicave but they only do movie stuff as far as I'm aware. Sentinel have a main line called Re:Edit, that produces some incredibly nice figures at about 1/10 scale, and Armorize, which has one release (and one exclusive repaint) in about the same scale as Mezco's figures.
Armorize looks nice but has some strange design decisions that really bring it down a few pegs as a toy. The Re:Edit figures are nothing short of amazing, some of the best engineering I've ever seen in a toyline. If you shop around you can actually pick up some of the regular releases discounted to around the $90-100 mark. As an Iron Man fan, as much as I want a "classic" comic armour, Mezco's figure isn't really doing it for me. The engineering looks way too simplistic for the price and I'm not a fan of the clumsy-looking panel lines added to the limbs.
AFAIK, its a mix. Sentinel and Comic Cave both made/make(?) comic Iron Men, but expect to pay a heft price. They also did movie figures. I think it was Comic Cave that released a Silver Centurion that looked like it walked off of a comic page. Never seen it in hand, only pics online so maybe it wasn't released.
They did release the Silver Centurion, by all accounts it's a pretty good figure. Not sure how it would scale with Mezco's offerings though, I think they're about SHF size.
