I think you'll find that most peoples "preference" is dependent on the type of vehicle they tow and the types of activities they use their towed vehicle for. If like us you use the towed vehicle for off roar travel a vehicle mounted towbar presents problems. It has to be disconnected and stored while using the towed vehicle. A motorhome mounted towbar stays with the motorhome so it needs no additional storage accommodations or space.
We use a Roadmaster Sterling All Terrain for our 2004 Jeep Wrangler. The towbar is lighter than most, but still has a 6,000 lb. capacity. It's versatile in that it can be connected or disconnected at significant height and angle differences between the towed vehicle and towing vehicle. That's not to say there should be a huge difference in towing heights (3" or less is the recommended height differences), just that the system can be connected and disconnected when the vehicles are not level or square to one another.
We also use the Roadmaster baseplates. They are flush with the front of, and at the same height as the frame rails when the bar is disconnected. For us this makes off road travel easier.
There are lots of different options. The key is to decide when and where you want to use the towed vehicle. Then it will be easier to determine what type and brand of towing system would best fit your needs.
