Is there a difference in the final model if there is a fillet on one edge and arc on other edge of a cube in the final STL file.Please note that arc and fillet are of same dimensions

It is the same radius, I make a sketch on the face of your piece, I use inches as a unit of measure, and it is a radius of 0.25 ", being the same on both sides.

There could be a difference if you use a better blending solution with the fillet.
A regular fillet will give the same result as an arc, that being a curve which is tangent to the two faces.
A conic based fillet will give a much better transition as it will not suddenly transition from a flat to a curve.
It all depends on what you are making, and how the end product should look and feel.
