>>8471110The Bandai one is wrong. The skull on the helmet indicates a Sergeant, but Ultramarine Sergeants also have a red helmet. Sergeants also have a white kneepad, which the Bandai Marine doesn't have. You can see both the red helmet and the white kneepad on the painted Mcfarlane figure
The little details, not really. The miniatures have the markings on the legs, and I think the Bandai does too it's just hard to see in that picture. I think the buttons on the arm are just a thing some of the miniatures have and some don't, for variety. I'd have to check though
