The reason for the existence of matt paper (genuine matt as opposed to silk, pearl, etc.) is that it is non-reflective at all viewing angles and thus ideal for display prints to be viewed under uncontrolled conditions. Matt paper has an intrinsically lower maximum density than glossy and so is never going to be the photographers' favorite!
For magazine reproduction, glossy RC is best. For color work though, if possible, slide/transparency film is best. We always had a hard time reproducing from color prints.
Every Instructor and Photographer (who has submitted work) that I have asked, say glossy is the only way to go when submitting. Some have even said that some Editors only accept prints done on glossy paper.
