Steel or aluminum ride will depend on the build. Some steel bikes will rattle you. Most aluminum bikes will (because of the larger diameter tubing).

With a CX bike, just run bigger tires and lower tire pressure and the frame material won't matter a bit. Tiny impact on rolling resistance, but not much difference in the big picture for efficiency.
