Mags' MCU helmet better look good. The best Magneto helmet we got so far IMO was the one at the very end of First Class with the bright colors and the big pointy horn, which we only got for one shot. The others that Fassbender wore look fine but the colors are always muted and the horn is always more subtle. Y'know what else we haven't gotten? That classic collar for his cape with the bolts on it. None of the movie costumes have had that. Graviton had bolts on his suit over on Agents of SHIELD and it looked fine there.
