I have printed hundreds and hundreds of 8.5x11" photos (my "snapshot" size..), mostly on Matte Heavyweight, and some on Photo Paper, and some on PGPP.

I have no problem whatsoever with the bright white of the Matte paper. It produces brilliant prints with excellent detail, and is much easier to view than a more reflective glossy paper. But it doesn't do as good a job with large near-continuous tonal shading, as in skys. Other than that, I love the stuff.

Cheers
