is it better to have the uth under the tank or on the side

Under it, they use belly heat to digest their food.

Just make sure you have an air gap at the bottom.

[B&B Geckos]

Under it. Leopard geckos absorb heat through their belly. The uth should only take up about 1/4 to 1/3 of the enclosure in order to create a temperature gradient. In other words, the gecko can now move from the warmer side (90 degrees) to the cooler side to thermoregulate. Place the hide over the uth and make sure to get a thermometer to take the surface temperature to avoid overheating your gecko.
