As an owner of the Mark III, I love it. To me, it's the more iconic (film) armour. But who knows, if I end up getting the Mark VII as well I may change my opinion.
Both!
They are both equally good
I own the 1:2 Mark III and the nostalgic part of me still prefers that armor over any other, but in terms of these particular statues I had to vote that the new one looks better.

All the 1:2 armors are a must for me
