So all in all....any full face helmet THAT FITS VERY TIGHT WITHOUT CAUSING DISCOMFORT would be fine. For caucasians I recommend Shark helmets...their lower tier helmests run about 7,000.
I think an easy way to look at it would be to consider a SNELL helmet one that was designed for a racing environment. It transmits more force to your skull and brain but is able to withstand more impacts. This is really important on the track where you may crash and tumble for a really long distance, continually smashing your helmet into the ground (been there, done that). The SNELL spec says a helmet must be able to take multiple impacts.
The DOT standard is geared more for the street. It's designed to handle one huge impact. This works well for the street where speeds are lower and the lack of run-off means that you aren't going to tumble very long (before you're stopped by a car, curb, sign-post, etc.).
In any case, I find the Taiwanese helmets to be frightening - a lot like the "beanie" helmets worn by the Harley riders back in the 'States. Impact protection is provided by the foam liner (the stuff that looks like expanded polystyrene, or the white stuff they use to package electronics). It deforms and crushes, absorbing energy that otherwise would be transmitted to your skull, and then your brain. Taiwanese helmets seem to have very, very little of this impact absorbing foam.
As for fit, you want to find a helmet whose interior gently but consisistenly touches all around your face. With a full face helmet, you should have continual contact through the cheeks, temples and forehead. You should "test" wear a helmet for at least 20 minutes. It should remain comfortable. You are looking for a snug, gentle fit -- not something that grips your head and leaves welts when you take it off. With the chinstrap fastened, you should not be able to roll the helmet off your head either forwards or backwards. The helmet should not be loose and flop around if you shake your head. A full face helmet is heavier and hotter but provides much more protection than an open face helmet.
Asians and Europeans generally have different head shapes. Because the foam liners can be changed by the manufacturers for each specific market, you may find it difficult to find a properly fitting helmet it you are not of the "majority" market in an area. Arai is the only brand I know that markets multiple head shapes in all its markets.
A helmet is the most important safety equipment you can wear on a bike. I've destroyed 4 helmets in the past couple of years in "loss of control" incidents between 15mph and 90+mph. Thanks to the helmets (all Arai), the least battered part of my body is my head!
