The 560's will have about a 160mm radiator advantage or about x1 120 + a 40mm radiator. I think the Mora with push/pull will be the better performer.
Depending on your heat load, they will more than likely perform about the same. Unless you are running an obnoxiously high heat load (or running no fans), I'm reasonably certain each setup will return the water to almost, if not ambient temps. What nuclear reactor are you cooling?
