I'm sure that there is a lot more research and development in the more expensive helmets. So even if they cost relatively the same to produce the better engineered of the two would be superior. I had a KBC that i bought in Korea (just to use untill my Shoei showed up) and it was HORRIBLE to wear. I was loud as fuck, buffeted (shook/wobbled) at high speed, uncomfortable, poorly ventilated, and heavy. I hated that helmet and it was one of the "high end" KBC's.
