As the OP can see, asking such a question is like giving a loaded gun to an infant, nothing good will come of it.  But you should understand when a primary content vendor decides to develop their own system after years of supporting the other guy, feathers will get ruffled.  Resentment sets in, then bitterness and finally us vs them.  As some of the others mentioned, it is high time to just use what works for you and forget comparing the differences between the applications and content.  Art is the final goal, don't open old wounds which will eventually lock this thread.
