I LOVE SC. Its so easy to care for. Neve rhas issues like fleece does. OV I think is the closet thing to natural wick away fabric. Its not as good as SC or fleece but does leave babys bum feeling drier than lets say cotton or hemp.
Both are synthetic and will provide a dry feeling for baby. IME, fleece is thicker and gets pilly, suede is thinner and stays new-looking longer. Unfortunately Z seems to get a rash more easily with suede than fleece.
Honestly, I prefer the fleece. Yes, the suedecloth doesn't pill like fleece does. And yeah, I think the suedecloth keeps baby a bit drier. But I just don't like the way it feels. I think fleece feels softer, and less "syntheticy," and for me the feel of it is more important than all the other positive aspects of suedecloth. Fleece, for me.
I prefer the SC. It doesn't pill and in the summer, when I was first trying out different materials in diaper construction, the MF felt a lot hotter to me when I changed a damp dipe. Plus, the SC is a lot easier to get if you live near Joann's fabric, and that's a plus! And it doesn't stain from diaper creams (I've heard MF stains worse).
i like both, the only thing that suedecloth does better is prevent staining. i have never had suedecloth stain, but i do have some microfleece that stained. i LOVE the buttery soft feeling of microfleece though.
