O.K. I'll bite.
Name one or two or three.

I have one too, and you're right about the no-insulation part, but the heat
transfer efficiency is what - 4x better? 8x? Efficiency isn't usefully
measured or compared without context. A side arm water heater could (have)
easily been used in a manner (I'm thinking of the Ingalls' family's
practice of bathing on Saturday evening) where the (considerably more
efficient) heat transfer efficiency more than made up for the lack of
insulation. Just as an example.
