Ultimately, the Bell is a little safer—with thicker EPS (the part that protects you from impacts) and a whopping five shell sizes. The Bell is also also larger profile, though, and in the toss-up between one 3/4 helmet or the other, it's hard to hew too hard on the safety argument -- they're both only protecting 75% of your head so the safety argument between the two is somewhat academic. 

All that said, for a knock-around city helmet for running errands in the summer, or something you're going to lock to the bike and won't be financially devastated if it goes missing, a 3/4 helmet is a viable option, and the Biltwell Bonanza offers a forgiving fit, light weight, and a three-snap setup at the brow for attaching any manner of flip, bubble or flat shield. You can also snap on a brim like the Biltwell Moto Visor, and/or any of our goggles options—ranging from the $35 Biltwell Moto Goggles through the $165 French-made Aviator T2/T3's.
