It's true I tend to prefer the direct trains to/from Gare du Nord, but this is more of a comfort issue (they are less crowded and they enable you to doze for 25mn without being disturbed by the stops). You may have to wait extra (up to 8mn) to catch them but this is partly compensated by the fact that the ride is faster.
