Any of those leaf springs will ride better than the Cat5. On my wife's 73 Camaro we removed Hotchkis leafs and installed the Cat5. Much rougher ride. tires make a big difference in ride quality too. With our race tires the car rode terrible on the Cat5's, with street rubber it was tolerable, still stiff but not as harsh.

I have replaced a couple sets of those Cat 5s for complaining customers (harsh ride) and replaced them with Hotchkis or DSE (lower rate and rubber bushings). There is a point where you get way to solid and stiff with leafs, especially for a street car.
