Another consideration is control drag.
On Airbus, the 'slip' indicator changes with an engine out to indicate when one is flying at minimum control drag - i.e. no spoilers out and ailerons neutral. Having centered the 'engine-out slip indicator' you will be flying at minimum control drag, but will have about 5 degrees bank towards the live engine, as mentioned above.
