It depends -- I know a real helpful answer.
I have bought mixed texture fat-quarter bundles from Robert Kaufman that were wonderful due to the theme -- Asian. The sateens really popped the gold accents in the prints. The extra sheen really worked well with the group and was that true wonderful something extra.
On the other hand, I have seen other bundles that included mixed textures (again all 100% cotton) and it was a real turn off. Instead of expanding ideas of what I could create from the bundle, it felt limiting. It as if the manufacturer is forcing what they could no sell down my throat.
In the case of the group you posted, I probably would not buy it. The mixed textures do not seam to give that "something extra" feel. The bundle screams for a fun tween quilt along the lines of Yellow Brick Road and I don't think the different textures would be a wow factor.
IMHO, in the end the mixed texture fat quarter bundles are one of those things that depend on what type of quilt is likely to be made from the bundle.
