How will A4 photo prints compare between the Nikon D3200 and the D5100?

The D3200 being 24MP and the D5100 being 16MP. I've heard 16MP is more than most people will ever really need. However I recently purchased the D3200, and my brother purchased the D5100 at the same time as we've both taken an interest in photography with the same idea - to print A4 photos. The question is, do you think there be a noticeable difference in the prints between the 2 cameras?

Megapixels are much less important than what most of us have been told. There are pros out there who have used as little as 6-8 megapixels and gotten good results. As far as the print quality, it seems to me that would have more to do with where you had it printed and on what kind of paper.
