Actually the Judge uniforms in the Stallone film were WAY off. Ignoring for a second the hilarious codpiece, the shoulder pads and badge were all meshed together into one unwieldy piece that always look in danger of riding up past the wearer's head instead of being three separate pieces, the under-suit was some kind of awful skin-tight spandex number instead of the more practical heavy duty looking uniform from the comics. Then of course there's the helmet...it works I suppose but the big visor never looked right to me.
By contrast the new design (assuming the test shot is more or less what they're going with) looks like a much better balance of faithfulness and practicality. For one thing the armour looks functional, like it'd actually protect the wearer instead of just look stylish.
One detail I hope they'll retain from the comics is the boot holster. It something that's often overlooked but Judges draw their lawgivers from just below the knee, not from the hip. It make a lot more sense when you consider that they have to be able to draw while riding Lawgivers.
