Yep, I'm a Bell head. They are not attractive, but they are generally the most comfy for me. I have an Alechera and just got a Metro for 'commuting'.

I also have a Giant helmet that I do wear when it is extremely hot out (extra good venting and it's white), but it's not as comfy as my Bell.

My husband fits better in his Giant than a Bell - so head shape really plays a big role.
