That's a good question about gloss and matte paper.
I was always a fan of gloss. Note I said "was."
Most, if not all, fine art photographers print on some type of matte paper, never gloss.
Depends what you want to do with your prints. When I was first starting out, as I said, I used gloss exclusively with my first printer, the Canon S9000, a 13x19 very fast printer. The results were excellent. A lot of the pictures I took now hang in the local H.S. wrestling room under nonreflective glass. However, now that I know better, I'm quite disappointed that they are on gloss.
Matte, when done well, with saturated colors (or high dmax B&W) looks much richer and displays better with no reflections. It is also usually heavier weight paper.
For my 4000, I have a roll of ultra smooth fine art paper. It is incredibly thick and the resultant picture looks like it was painted on. Once it is framed, it is truly a work of art.
Your best bet is to experiment with different paper types until you find what you like best for a particular circumstance.
A former friend of mine (I should really say acquaintance) who was the subject of a post a while back that you may remember, wherein I lamented working a long, hot day and him not paying me that day?) prints all his sports photos on gloss paper and it is very impressive to the customers, even though it may not be the best choice.
I also like semigloss.
