Quoted from GravitaR:
Played an BKSOR LE tonight at Pinball Pete's AA and ball got stuck on upper pf behind the flipper multiple times. Also was getting stuck halfway up the Left VUK on some plastic before the exit to the upper PF. The ball getting stuck behind the flipper in a hole is a design oversight. How that wasn't caught in testing is anyones guess.
So Dp gets my vote by miles.
Never had a single ball stuck on my LE. That was not a design oversight, apparently there were a few games with a missing washer or something. Not sure what the other one is but never heard of anyone else having that one. Probably something that would be fixed in ten minutes in the average home use environment. But you're right, I'm sure no Deadpool ever had trouble out of the box on route, so it definitely is a better game.
