Why 3/8 hose with 1/4 fittings?

by Steve

Mostly I see a variety of these offered in local stores (hardware, automotive, etc), versus 1/4 inch hose or 3/8 hose with 3/8 fittings. I've tested the two (filling one tank from another) and for 50 feet, which is the most common length sold, there's no difference between 1/4 and 3/8 both with 1/4 fittings, so why is there a greater demand for 3/8 hose when the most common fittings are 1/4? Is this a common misconception, or does that combination perform better in other situations? I'm thinking all components would have to be 3/8 for the hose to perform differently than 1/4 inch.
