My favorite Iron Man figure so far was way back with ToyBiz's series 8 figure. That thing was amazing, and I regret selling him to this day.

If you prefer the classic look, you really cannot go wrong with the one from the Maria Hill two pack, as he was pretty awesome as well, although he might be too small for your tastes.

My personal favorite Iron Man suit of all time was his look from The Ultimates, which Hasbro attempted when they took over the line, but they weren't even close. I wanted the Marvel Select version for a long time, until I finally had it in hand and saw how big it was in scale to my legends. Still, it was a really wicked design that I dug a lot, and is one I'd like to see done properly at some point in Legends scale. They nailed it with the 3.75" Iron Man 2 line, I can't see why they couldn't do it again.
