I've seen some stuff printed on fiber and I can't see anything magical about the emulsion, but I do see it crinkled up.
There isn't anything magical about the emulsion. The paper texture and the feel of the paper are what drive most of the opinions you've heard. There is also the tonability.
Now, if you see crinkling fiber, then that print simply hasn't been finished properly. A dry mount press eliminates paper warp entirely. I used to do all kinds of things to try to get my fiber prints to dry as flat as possible- squeegee, dry back-to-back, dry slowly in a humid room. But I quickly abandoned that in favour of just interleaving the [almost 100% dry] prints with tracing paper and putting them in a dry mount press... without mounting glue, just using the press to flatten them. Come back the next day and voila.

Heather, if I gave some sort of elitist impression then that was not my intention. The question was who does FB and why and I gave my personal unvarnished (or should I say non RC-coated?) opinion. The first prints I ever did were fiber, just by chance, and that was that, I was hooked. I did try many RC papers and use them for paper negs. It is true that there are some wonderful RC papers. It's just that in general, I tend to matte/semimatte FB.

Eddie, regarding your question about washing, I would think that if anything, your cut paper would wash a little bit faster.
