I suppose the emphasis is the most important consideration. Is saving a few ounces of fuel the critical issue, or something else? For us, we use reverse because our braked landings in autobrakes reduce the braking in proportion tothe amount of reverse. That is, land with greater reverse, land with less wear and tear on the brakes, and cooler landing gear. That means shorter turn around times, and there's really no time around the clock when the airplane isn't getting turned to go back out again. It never sits, and the limiting factor as often as not is brake energy and temperature.
Accordingly, it's more economically sensible to use the reverse for us, and as low a brake setting as possible, given our weight, the runway length, and ambient conditions.
