Ive used both now, and have heard conflicting stories on which is better.
I started out with a heatpad under one side of the tank, but it didnt really raise the temps enough, so I switched to a heat lamp. I now currently use a 60w daytime bulb which keeps the air temp around 78, and a 50w moonlight bulb for night, bringing the temps to around 75.
I just want to know the majority of this community uses. Ive heard anywhere from heatpads can burn your pacman and that heat lamps will dry him out.
