actually it will be hell lot better than this one,since we didn't really see good fights because of the juubi doing all the work for madara and obito.
If it happens after Madara/Juubi are somehow defeated, it will be anticlimactic however it happens (unless it involves Sasuke getting a Juubi related powerup or something, e.g. becoming its jinchuriki).
My opinion is that it is gonna be the best fight ever in Narutoverse, they also have a lot of new powers that they didn't show yet.
