I have the plush ones! Overall, recommended. I'm late for work but I'll update later with more info. Also, Anjali at goldenmeans reviewed a bunch of warm tights when she went to Paris last year in the dead of winter--some creative googling might turn up more info before I find the link--and also liked them (which is what convinced me to take the plunge).
ETA: The Plush ones are fairly thick--what I like about this is that they are very very opaque. When I bought them, they only had s/m and m/l and I was on a sizing-up-in-tights kick, so I got the m/l, despite being on the very low end of that sizing range. In retrospect, this was probably a mistake, since the only thing I don't like about the plush tights is that I tend to get ankle wrinkles which is not so cute. The waistband is thick but not tight? So there aren't any rolling problems. The texture is a little more shiny than normal tights, but stretched out over your legs, it's not really noticeable. I decidedly do NOT find them as warm as pants. But they make skirts bearable on days when they would otherwise not be.
