I think the RCBS Rockchucker is the stronger of the two presses. I also like the fact that the Rockchucker has an optional Piggyback unit that converts the single-stage Rockchucker into a progressive reloader if desired. I don't know if the Orange Crusher has this option. There's always the Dillon AT 500 Reloader. It's also upgradeable. Just something else to consider.
