Both have products that are good, both have products that suck. It's best to take things on a product by product basis. For heating pads I will say that I swear by reptile basics under tank heaters.
I'm new to BP keeping and even after a lot of reading/research thought I could make an exo-terra glass cage work with a UTH and heat lamps. It can work but it's not easy and maintaining humidity is difficult, I'm misting all the time to stay above 50% even with most of the screen top covered.
If you're on a budget go the tub route otherwise get a plastic enclosure with a RHP or UTH or both (Boaphile, Animal Plastics, Vision, Reptile Basics...)
