I think the best thing Sentinal really had going for him was that no one expected him to end up a turncoat. Recent IDW Ultra Magnus is like, constantly looking for potential threats, so he might not be lulled into false confidence by a gracious-seeming Sentinal.
However, if we're exclusively talking cartoon, "I can't deal with that now" Magnus, I'll vote Sentinal. Magnus may have been a heavy hitter, but a few blasts from the Sweeps was once enough to do him in, and Sentinal's pretty handy with that sword, and if he uses that acid rust gun thing, there'll be a small pile of Magnus left over.
