In my opinion, both the AUH and a Trailer Saver hitch are quality products and will get your trailer to your destination. They each have their upsides and downsides such as cost, weight, installation, hook-up methods and so forth which the OP will have to judge the importance of on his own.
One thing that is evident is the Andersen hitch is a solid hook up between the trailer's pin box and the truck's frame; no give. The Trailer Saver incorporates a soft joint. In terms of towing comfort and gear protection, Trailer Saver wins hands down.
