I pretty much only use Agfa RC now (semi matt). I love the finish which is what I'd called a low sheen. Less than Ilford Pearl and no texture to the surface like Pearl has. Last time I bought some, I bought a 250sheet box I bought some glossy when they has a 125sheet box for the price of 100, but I use that for contact sheets as I don't like glossy finish really.
I have just got back into printing some FB and have some Ilford Warmtone (yuk! paper base to yellow for me), Forte (VC and graded) and Sterling (VC). Not enough prints to comment on the FB and need to set up some drying method!
I use Ilford Warmtone for still life and landscape but prefer Oriental Seagull Graded for street and documentary photography. I still have a stock of Kodak Ektalure and the old Agfa Record Rapid in the freezer and love it. Fotospeed have just introduced Legacy a new Fibre VC paper. I've made a couple of prints on it and first impressions are that it is very nice but will let you know my verdict when I have fully tested it. I only use fibre papers.
Nige, the yellow base that you mention may be caused by over washing. I have had the same experience and agree that it is yuk, but found that careful timing of washing cured the problem.

My favorite FB paper of the moment is Cachet (Maco) Expo graded. It's just slightly on the warm side, tones and bleaches well, holds shadow detail very nicely, and has rich blacks. You can order it in the U.S. from freestylecamera.com.
Galerie graded has more brilliant whites, so I use it occasionally. I also like Oriental Seagull graded. For prints that do better with split-grade technique or that require some contrast grade I don't have, I use Ilford MGIV FB.
Azo for LF contact prints.
Ilford MGIV RC Portfolio, when I want an RC paper, usually for small snapshots that I give away unmounted.
I too have been using Ilford MGIV fb exclusively exc. for rc for contacts. I like the rich blacks and whites. I haven't tried the warmtone paper yet, but I want to print some landscapes on some to tone and experiment.
