I'll still stand up for RC paper... partly because I do alt process and my cyanotypes are similar to FB type prints as far as matt finish or whatever finish I have on the type of paper I use.. however, my cyanotypes do not curl like a #$@%!! I think the curly stuff really ruins FB for me besides the additional dev, fix and wash times. I tried it and it wasn't worth the effort (strangely, coating paper for cyanotype is less effort too and I find developing enlarged negatives in total darkness more fun than trying to soak fix out of an FB print).
I find RC prints quite fine and probably all of the people I know wouldn't know what the heck an FB print was if I gave them one. They recognise RC as being a photograph.
