Yes, it was #1 basically all the way up to Civil War. Honestly might be more of a three way tie at the top for me at this point.
It's the definitive suit of the bulkier Phase I mechanical look, before moving on to the more industrial look of the Phase II, to the organic look of Phase III.
Being able to see that evolution on screen and with these figures is just such a great experience.
Wasn't the 45 the first "organic" suit which was introduced in Phase II in 'Ultron'? What were the "Industrial" suits in Phase II? I find this very interesting, I've pretty much only considered either "mechanical" or "organic" as the divisions for armors.
