I haven't done any experiments on comparing the two approaches, but my intuition tells me that setting the demand heater temperature setting lower, to shower temperature would be the most economical.
I am amazed how thrifty a gas demand heater is, when it is set properly. I take a long hot shower every day, at least once, and sometimes more, and my gas use charges are lower than the charge to read the gas meter.
