Plate diameter and thickness affect a gym as much as the number printed on the side. A thick bumper can fill a sleeve early. A small-diameter iron plate changes the starting height of a floor lift. Plan the combination rather than buying by total pounds alone.
Compare the differences below against your needs. These are research-based selections, not claims of hands-on testing.
