In a nutshell, proportional thermostats are considered to be better because they allow the heating element to be "partially" on. This makes the temperature stay at the desired degree more reliably. The heating element isn't just turned on and off, the thermostat raises the power level to the element if the temperature is too cold, and decreases the power level if it's too warm. This makes the heating cycle far more accurate and have less dips and peaks below or above the desired range.
On/off thermostats click off at a high temperature, and then the temperature has to fall a few degrees before the power is turned back on. The time it takes for the heating elements to heat back up from an OFF state and then warm the cage up a few degrees can cause the temperature to fluctuate quite a bit over time rather than staying at a constant level. The temperatures could bounce from too-warm to too-cool and back all day long. ----- Lauren Madar - OphidiaGems.com
