I have the B&W Companion slider (3405) in my Ram 2500 and love it. Very easy and quick to hook up and there is never any doubt that there has been a positive engagement of the jaws. Unhooking is even easier.
My friend has a Curt Q24 in his Ram 3500 SRW and while it has always worked (eventually), he has had a few more issues with his. Typically his issues are with getting the jaws to lock and unlock. It can take some finagling at times to get it to work properly.
For me.... I'll hang onto the B&W. It's been a breeze.
