this question was already addressed. Back then I thought it would have been the exact same. Yet now I know there are slight differences.
The base of the extender makes it so the pull don’t directly hit your ligs, as opposed to hanging Straight down. Plus the extender makes the dick kinda bend on the base and then pull the shaft out, while the hanger just goes straight pull, no bends. This might seem like a very small difference yet it changes the angle of attack, so the strain in the extender I believe is more shaft oriented while the hanger is more base oriented, if that means anything to you.
