The benefit of having the mouthpiece in the center is that people who think it makes a difference won't hassle you.  Personally, I think you should put it where it works best, wherever that may be.  My trombone mouthpiece is extremely to the left.  I moved it there from the center when I discovered that it worked much better there.  Better endurance, range, and tongueing.
