I still occasionally print on glossy papers, so I do not completely rule them out as being preferable for certain images, but you have to get the lighting and viewing angle just right to enjoy the full benefit. I would add that surface reflections on glossy paper effectively reduce color gamut and Dmax, in addition to being distracting to the eye. With matte papers, reflections are not a factor, which can make the image look purer and deeper, despite the limitations of gamut and Dmax. In the end, it's an aesthetic choice.

Ten or twelve years, printing with my dye-based i9900, I found the most intense blacks I've yet to see on Ilford's light and porous (but 13mil) 230gsm Fine Art Smooth matte - simply black holes you could fall into! In fact I won "Best Color" in a sea of glossies with it in a regional show, and the below posterized image's fluorescent greens and reds printed beautifully.
With my pigment based iPF's of the past six years I've found that raising the black level to clipping level and usually slightly beyond guarantees not only the best blacks, but also the most vibrant colors on my current Innova Photo Smooth Cotton archival matte and also RR's Polar matte I use for proofing.
I do admit to frequent impure thoughts of resurrecting the 9900!
