My boat, and pretty much everyone I fish with runs Smooth Moves Ultras. I like them. They are in fact heavy and bulky, which is the only down side I see. Some people say they have a "launching effect", but once adjusted properly for the weight of the passenger, this is not an issue. I sold several sets when I was in business. They aren't cheap, and you don't see a ton of used ones for sale, so I must assume people like them. I know I wouldn't be without them. I have not tried any of the other brands, but do not like the idea of having to use an air pump to adjust them. I also didn't like the way some of the other locked the swivel. With the SMs, you can adjust on the fly if needed.
