I'd opt for comfort height and add the CEFIONTECT. The ecco version might get you a rebate from the utility company, and if nothing else will save on water and sewer charges. Many of the Toto toilets are a take-off on the Drake, so style might dictate a different one. The cyclone rinse probably does a better bowl wash, but the Drake does fine for most people.
Different styles and colors other than white add cost, but when you live with it for 20-30 years, the difference is minimal.
