That's hard to say. I definitely can see what people are saying in that regard, but there are photos where that isn't the case. I think a lot comes down to pose work and the angle of the head. It's a little tall, but not too far off. Keep in mind he's slouching his neck down here, something the fig can't do.
From a subjective standpoint though I think that the roundness and simplicity of the traps on the armor accentuate the sculpt. With other suits there's always more to be looking at, but the space age smoothness brings you back to the organic human providing such a stark (pun unintended) contrast.
I absolutely think the figure looks better than the on screen armor.
Right now the only armors I've got out are the 43 as he pairs with my AOU Cap and my Shotgun as the pose as I am hooked on the flight pose I've got him in. I think the lack of helmeted appeal is a subtle product of the way the films and marketing are presented, more often than not we see Tony helmetless or with a cracked dome. The exception seems to fall when dynamic poses roll in, which certainly favor the helmeted appearance.
