I found that even within the same brand, different models can have a completely different fit.
I've been wearing a Lazer Z1 that fits me perfectly...decided to order a G1 because I like the styling better. It turned out to be a completely different shape and fit. Found that with POC, too. I wear a Tectal Race Spin for mtb'ing...tried on one of their road helmets and it felt like I was wearing a square-shaped helmet.
