Only someone who has tried all makes of heater liners could actually answer your question. That being the case, I can't answer it either but I can say that my Gerbing liner and controller has been excellent. In fact, a wireless controller was recently introduced and I'm now using that. This has greatly improved the convenience of controlling the liners since it features a wireless battery-powered remote transmitter mounted where I can easily reach it. The receiver control module stays in my liner pocket. For me, this was a game-changer.
