I have the B&W Companion OEM which uses the factory under-bed mount. It's my only 5th hitch experience but am totally satisfied with it. I have a More-Ryde pin which helps keep things quiet and smooth. I ordered my hitch from a web supplier (don't recall which one) and the assembly/install was minimal. Note that I pull with a short bed and this hitch is a non-slide. To do over I'd get a slider.
But, at the end of the day I like the B&W.
