I have also been posed this question. Aerodynamically (apart from the crosswind mentioned before) there should be no difference. There is however a difference measured by what systems are supported by which engine. In some aircraft the hydraulic systems supported by each engine may result in a downgrade of the controlability if say the right hand engine should fail compared to the left hand one. This may be considered to be a critical failure as a result of some downgrading of your redundancy, or reduced controlability.
