Can’t really give advice, but can give my opinion…
I have the Shoei XR1000 and I’m very happy with it. It is very comfortable and has pretty good ventilation. It’s the only helmet I’ve had so don’t have anything to compare the noise levels with, but it hasn’t been a problem around town. If I head out for a ride then I just stick in some earplugs.
My only advice is to try them all on, doesn’t matter what the spec or reviews say if they don’t fit properly.
Generalising a bit each manufacturer has a shell shape and they vary, so I fit perfectly in an HJC but can’t in an Arai or Shoei, so no matter how good they are they’re not for me.
Motorcycle magazines say similar to the above. It’s most important to get one that fits and different manufacturers are different shapes. You may have an Arai head or a Shoei head. Some people buy the same brand always because that’s the one that fits.
As I understand it (and someone can correct me if I’m wrong) they all need to achieve a minimum safety standard to be sold. Thus more expensive lids are more comfortable, quieter and look nice but are not necessarily safer.
I have a raid II, it fits it’s comfortable and you can et some fantastic deals (under £200 for a graphic design) Also it has the pinlock as standard which is absolutly fantastic
