Personally, the Movie figure is much better based on cost alone. They're pretty much even on accessories. More detailing on the revoltech as well as range of motion. The movie version has a lot more umph, just check out the leg armor, the revo one looks scrawny. The movie's gattling gun slides across the back, but the revo has more poseability. One thing that revo doesn't have is the shoulder rockets, though it does have those blast effects.
The 6 inch movie figures have been re-branded as The Armored Avenger, and should be available at TRU and Target. If you don't have those over there, you can surely get them from like RobotKingdom, BBTS, and other online stores. :thumbs:
Not at Target Australia yet, but I've not been to a TRU in ages--mainly because they're always int he outlying malls outside city limits. Maybe I should check them out over the weekend...
