I ride motorcycles currently and use full face helmets. A motorcycle helmet will be too heavy and cumbersome on a bicycle.

For moto helmets in general they do not limit peripheral vision whatsoever. I even use mine with sunglasses and there's no loss of vision.
Wind noise is dampened as the air is not forced around your ears but several inches away around your helmet. Some helmets "whistle" a bit but it depends on brand and what vents are open.
A "pudding cap" doesn't offer much protection at all much of your head/face is still exposed to whatever impacts it.
