My favorite is Shoei X-12. I have had Arai's and HJC's. I hated the Arai's shield system and the HJC put too much pressure on my forehead.
In my opinion, the most important factor is correct fit and comfort, as mentioned by many others already, no amount of discussion on this forum can replace trying on the helmet at a dealer. I have never mail ordered a helmet.
