Yeah I would agree that with the factory pucks using one of the hitches that drops in them would be the cleanest. I think the factory Ram version is made by Reese. The aluminum hitch you read about might be the Andersen but the downside there is it uses the gooseneck ball to attach and I don't think that's quite as solid as using the pucks. I love the Anderson hitch and actually use the rail mount version myself, but I don't like the gooseneck style as well. I suppose another option would be a rail adapter coupled with the rail mount Andersen. That would save some on weight and be easy to install/remove.
