I agree overall...
HOWEVER, after taking a close look at both, I have discovered many things that Marmit got right. They really did their research.
The Marmit helmet is wider. The proportions are actually better, but the softer plastic mold hurts. Marmit even got the "nose ridge" correct, where SS completely left it off. For those who don't know the "nose ridge" or whatever the proper term is is the raised part between the eyes on the "nose" before the ridge reverses to create the "bags" under the eyes.
Also, the Marmit thigh armor is better proportioned -- SS thigh armor is very long when compared -- though both have the same height shin armor. Similar situation on the forearm armor.
The actual "chest" chest mold is also better scale on the Marmit.
So I have to tip my hat to Marmit for these little details.
I still feel that overall, to my eye, the SS trooper just looks better... even with its inconsistencies. But Marmit does hold its own in many places.
