I've bought several Pixie pants over the years. They've tried various fabric mixes, but my favorite has always been the one made with cotton and spandex only. Most of those seem to be replaced with a new cotton/rayon/spandex line, so with no other option, I tried them out and here's how I think they... compare. Pros: more pigmented, more of a sheen which may be good for office, seems to shrink less in wash Cons: collects lint a bit easier, more drape but less soft, material loses versatility for casual wear, baggier Cut/sizing: true high waist (pro for me, maybe con for you), bigger (enough to go down a size), excessively long (ankle cut may be full length for petites) Ultimately, I preferred the versatility and comfort of the cotton Pixie pant. This is still a fine pant, probably best for business casual wear, but I will hold off on buying more because of fabric and fit/length unless I notice an update or change in materials.
