Ilford Multigrade IV-FB is a good-quality, fiber-base paper. As far as tonal preferences goes, that is largely a matter of personal taste and film choice. I use this paper for Tmax-400 negatives developed in D76 or ID11 1+1. My paper developer was Dektol and is now Agfa Neutol WA. All this works well for my type of photography (see my website).
For me, paper curl is not an issue, because I have a drymount press. There are numerous threads on APUG, dealing with paper curl, and I cannot add anything to them
