I had to borrow a helmet for a ride recently; it was a Lazier with more vents than my helmet. But what I really appreciated was the better sightline from how it sat on my head. When down on the drops, I didn't have to tilt my head quite so much to see down the road. That was a real quality of life enhancer on a 300km ride.

Just saying, vents and looks aren't the only thing that matter.
