I like the Recon helmet a lot. I want to get the Recon SURG helmet, but the requirements to get it are so stupid that they defy logic.
The Recon looks a little more classic, but now they've added bulging cheekbone flangs on it. I don't even know, why 343? I am thouroughly dissapointed with the helmet assortment in this game. The default helmet is cooler than most of the helmets, and the coolest looking helmets were exclusive preorders, or cost 400$. Not. An. Improvement.
