I think there is, although it's less noticeable under glass. There is a difference in print longevity, though. The extra time in producing a fiber print will ensure that it lasts. In the grand scheme of things, the extra effort involved in making fiber prints isn't that much, when considering the print's lifespan. For me, the few minutes saved, using RC paper, isn't worth the potential loss of image quality over the decades to come.
Interesting, I'll give FB a try after I run out of RC this time.

There are adverse conditions that RC may withstand better than fibre based paper.
In either case, if you properly process and finish and store/present your prints, they will last for a long time.
I print RC almost exclusively. I like the results I obtain. If I had a dedicated darkroom and a reasonable amount of space, I would use both.
I went to a gallery showing today and they had a number of prints of musicians from all different time periods. They were all framed and the process labeled. They were all large prints, over 20 inches, and I really didn't notice a difference from RC or FB paper. There were RC portraits from the 1970's that were side by side to FB and "archival pigment transfer prints" which I think were modern inkjet prints. I didn't see any noticeable difference or degradation of the RC paper, and that was old paper from the 70's. It was labeled as RC, but that was the only visible difference, at least to me.
also, RC PAPERS ARE MORE FORGIVING to processing mistakes such as under washing than FB papers.
I'm a seasoned FB printer but appreciate RC's ease of use and nice flat laying qualities and feel. Nice for small prints, 8x10 and 5x7. Larger prints look and feel better on FB. But I've been intrigued by Portfolio RC for sometime and may have to try it out. It may change me over to RC for most of my work, as my time of late is much more limited.
