Turning towards a dead engine is slightly riskier in that it would be easier to 'depart' after overbanking,but it makes turning far easier. Trying to turn into the live engine can be harder work, but safer.
I was at Franborough in the 60s when a Breguet Atlantique doing a low level display on one engine unfortunately did a 90 degree bank into the dead engine and lost it. Easier turn, but far riskier. As for stalling a lower wing, I think it makes no difference.
