well all helmets protect your head equally. any helmet claiming to be better has no validity to this claim as their is no additional testing past the baseline test that all helmets pass. That said popular looking helmets companies are R.E.D., POC, smith, sweet protection, and bern
Alot of people on here love the Smith Holt, myself included. It isn't too expensive, works well with goggles, and has a great liner to wear a beanie underneath. I had a POC receptor before which was much more expensive and liked it, but I like my holt more.
