A big factor in the helmet equation is how much time you spend on your bike. A top end helmet like the Schuberth is relatively quiet compared to the other helmets and it has nice features such as a retractable sun shade.
It was real hard to find a dealer with a selection of Schuberths so I could try them on for fit. No one in Oregon had them. The shop that had a selection was BMW of San Francisco and that is where I got mine.
