They generate a different result if the "Centroid Triangulation" style is on (which it is by default). That's settable under moi.ini under [Mesh Export]:

[Mesh Export]
CentroidTriangulation=y

When that's set, then for "Quads & Triangles" output, when possible an additional point is added to the centroid of the n-gon and triangles are formed by connecting to that, making a kind of radial triangulation.

When you are doing "Output: N-gons", the display mesh that MoI generates for the n-gons does not do that centroid style triangulation.

So you'll only get an exactly matching display in MoI if centroid triangulation is turned off.
