I've used the regular nomex, and carbon. haven't gotten to test out either really well in a good hot fire. I've heard bad things about the carbon ones letting heat through or failing, but not sure on all the details.

In a helmet, there is no difference in the material. Any fiber (Kevlar, fiberglass, carbon fiber) is bonded with a resin. This resin, not the fiber, is what tends to fail under high heat. If the helmet is NFPA certified, then they all offer the same impact resistance.
