Re: Titanium Man or Crimson Dynamo?
^CD would be the better choice for a more similar sized armored foe, at least if we're going to try for comics accuracy. TM has always been larger(but not as big as Iron Monger in the 1st movie) since the 1st wearer needed a bigger suit due to him being a 7 ft tall guy to begin with. So while the suit was larger, it wasn't oversized for the original wearer like Stane's IM armor was. CD's suits however have alternated being larger than Iron Man and the same size depending on the version of the CD armor. So go with that.
