There are positives and negatives.
I believe there was a post about it on here a while back. The Super AMOLED displays use a different subpixel ratio, I'll link the image to it:
This is a pic of the Galaxy Note 2's subpixels which uses amoled:

As you can see the red blue and green are all different sizes, this gives not so good colour on the screen as well as the "pixels", not....um....accounting for as much I guess? So the quality of a 441PPI IPS display would look better than AMOLED, the sub-pixels are smaller, and more even.
Sorry the second part was explained very well, anyone want to add anything, or correct me, do so?
