I currently use an Arai - I have an 'Arai' head. I've tried Shoei in the past, but they just don't fit me well.
If you want the vintage look, Rockhard has a line of 3/4 helmets that are reasonably priced. I have one in red metalflake and wear my Halcyon goggles when I wear it.
I like going to a shop where you can try on different helmets. Doesn't matter what the reviews or prices are, if it doesn't fit well, you're not going to be happy. In my area we have a local shop, Competition Cycle, that carries 8-10 brands to choose from and try on. We have Cycle Gear, too, who have a more limited selection in their store, but also allow you to try on various lids before you buy.
