Mathematically they’re equivalent, but the feelings could not be further apart.
As one on an extended hiatus due to getting hit by an SUV and high-siding, I recommend only using a full face or highly rated modular with a good lock. I have a face because of my HJC modular and am not confident in anything without a chinbar.
I’ve often wondered why people gravitate so much to quarter and even half helmets for this reason. They do protect your head better than nothing but also expose your face (in the case of a quarter helmet) to the ground.
I suspect that, for some, it is the misconcption that the visor limits field of view in a meaningful way. Might have been the case 40-50 years ago but seems a rarity with modern helmets.
Back on that site that sounded like read it I asked some of these people and it just boiled down to “because I can/freedumb”.
