I like my Nutcase helmet. Sure, I get some pretty funny looks from time to time, but I've actually found that motorists tend to notice me more as a result. A nearly 40 year old, big, bearded dude rolling along on a sleek German cyclocross bike with a big ol' 8 ball helmet isn't something you see just every day.
I wear a 7 5/8 long oval hat and found that Specialized and Nutcase fit really well. Bell, Fox, and Giro didn't sit quite right. What I dig is that the Nutcase is comfy, well-built, and solid. The magnetic latch system is just sweetloaf with sugar gravy. My only two criticisms are that they're a bit heavy and I can't figure out how to adjust the straps so that they don't hit my ears.
I may not be as fashionable as some, but my daughters get a kick out of it, it's comfortable enough that I'll wear it even in 100+ degree Texas heat, and I enjoy the delusion that I'm a bit better protected.
