Curt vs B&W hitch ?? Same as Ford vs Chevy.
Both are top hitches for light duty work such as pulling a rv.
Hitch brand/truck brand comments are alway amusing from those who have never owned the product or I had one back in the day.
Keep in mind popular doesn't always = best bang for the bucks ie; ST tires being popular.
I would choose the one that best suits your needs.
