FWIW I went looking for a new helmet this year. For the last 10 years or so I've had Nolans. Been satisfied with them though they are noisy, but I do have to admit that i threw away the under chin guard which I learned very recently has a significant impact on noise reduction.. Never said I was smart.
At the NYC motorcycle show I checked out the new Schuberth C3 with high expectations. Bottom line I was very dissapointed. The quality is no better than the Nolan, it is lighter but I tried on 3 and none fit well at all. I tried to get the attenttion of a salesperson with no luck. Maybe I missed something in the fitting but I left there think Shuberth is way to many $$$ for the quality.
The Sheo Quest was nice but I have to say I was smitten by the Aria RX-Q. Great fit on the top of the heat and then you adjust cheek pads to get them just right. Very light. A bit more $$ than I hoped but the quality and fit were perfect.
Came how a bought RX-Q...waiting for the two foot of snow and ice to disappear and try it on the road.
If you can live with a full face, the Shoe Quest and Arai RX=Q are worth a look
