MK Sentry wins in morals and loses out of them.
New Avengers Sentry loses 9/10 in morals, since 1 time he could choose energy projection. Planet level attack will at least KO Superman. Out of morals Superman wins 10/10 thanks to better reflex.
Sentry-Void stomps, Superman can't harm him and Void can one-shot him with wave of his hand.
