It would be better to compare only those aircraft that are approved for ETOPS.
A 737 is not approved for ETOPS so its reliability does not play a role in the
question.

Also, As for shutting down the wrong engine.  Do you know the details? Was it
crew error? Was it caused by confusion due to the cockpit design?  Without
these and other details any comparison for use in the original question about
ETOPS and reliability are meaningless
