I use it for academic botanicals and natural history to get high contrast and popping fine structure. I accept the glare problem. I have an Epson and have used Epson ultra premium high gloss, and also some Illford high gloss papers. I've also have used some pearl paper, and find the lower pop not ideal. Matt paper would kill my subject matter.
As with anything it has a lot to do with individual preference and specific application rather than good vs. bad. Try to get fine detail on rag paper and you are out of luck. If you want to get a hand-crafted feel, high gloss is not ideal.
Get the appropriate paper profiles and use a calibrated display to get best approximation.
