Radiant Heat Panel v.s UTH

Hey im getting my snake soon and I'm going to be keeping it in a 48qt sterilite tub, I was wondering what would be better for heating the tub, a radiant heat panel or a Under the tank heater :confused:

UTH hands down.. they are thinner and will work well under the tub..

I would also say UTH. A RHP is more for tanks or vertical enclosures in my opinion.
