You can get a glossy finish with glossy fiber based paper by ferrotyping. It's not as easy as RC, but the finish is glossier.
I have my doubts about the longevity of RC papers on display. I have seen some prints from as late as the early 1990s that have silvered out after a few years framed in normal room light. If the prints don't need to stick around for more than a few years (proofs, headshots, promotional shots, prints for reproduction, etc.), RC is fine, but you don't see much in the way of B&W RC prints in galleries.
If your goal is mainly to produce a clean looking product at low cost, and you like the look of an RC print, then stick with it. I'm also like Ann, though, in my preference for the look of graded fiber papers.
