I don't care if Naruto wins or loses. I just think it would be more interesting than Naruto defeating Madara when he gets whatever power up we are waiting for
Better is subjective to each individual, a general consensus at times is more reliable than that of a professional opinion[depending upon the source]. Only you can determine what is better within your mind alone, but that does not necessarily mean it shall qualify as a great anime on a system of standards, popular top tens created by collected minds, or reviews by companies. Objectively however, you can ascertain the strengths and weaknesses of any matter and qualify it based upon such, and still state you didn't like it regardless. Does that mean it is a bad anime? It is simply your individual opinion in comparison to a general consensus, as well an objective perspective. Many reviews attempt to act objectively, however many others simply strive towards feeding and influencing public opinion.
But Really, What would be the problem if Madara wins ? Madara is Successful and Part 2 ends. Part 3 starts describing Naruto's life in MT. Naruto in MT would meet the Rikudou, Gain a power up and Break the Genjutsu and finally Defeat Madara. Then there would be afinal showdown between Naruto and Sasuke on whether the Juubi should live or be destroyed.
