I am late to this thread. I use a Rockhard 4X4 rear bumper and swing-away tire carrier with jerry can mounts. The welds are good, as is the finish. It does not rattle or squeak. The swingaway latch is easy to use. I use a "skinny" 255/85R16 spare rather than a full size 315/75R16 to keep the spare tucked a bit tighter to the tailgate and save a few pounds.
I am in general not a fan of tailgate mounted spares because hanging that much weight on side opening tailgate hinges can create more problems than solutions. I have no issue with a swingaway carrier that doesn't rattle or squeak and can handle the weight of the spare and jerry cans without sagging when the swingaway is open. In that aspect the Rockhard product is better than competitors' with swingaway design.
My opinion of the Rockhard 4X4 rear bumper system is positive. I have no complaints. Whether or not it is the "best" alternative is purely subjective. Internet debates over whether a product is "the best" typically quickly degenerate into meaningless pissing contests that I am not interested in entering.
My opinion is that the purchase of the Rockhard 4X4 bumper and tire carrier would not be a mistake. Whether it is best for your purposes is something only you can decide.
