Keep the intakes out in the clean air ahead of the wing. Keep the exhaust sonics shielded from the cabin by the wing. I think there is an element of balancing the CG of the wing as it is sharply swept backwards. Ease of maintenance, wing bending relief. Cons- pitch power coupling, ground clearance issues, spoiling wing for high lift devices, asymmetry.
Engines above the wing have not been a success. VFW614 had engines perched on top of pylons on top of the wing. Must have been noisy and restricting view. Honda Jet yet to prove configuration works. Risk of severe damage if engine breaks free. Exhaust interference with tailplane.
