Generally speaking, a direct plunder of the same size is twice as powerful compared to a reverse plunger (because of the amount of air they can push). Reverse plungers have more chances to leak air too, so that makes them even less powerful. Direct plungers without plunger rods are also the most powerful for the space they take up.
