I don’t care for Red Heart super saver because it’s just too course for me. I don’t like the way it feels when I knit with it. The Red Heart soft is nice, though and similar to Simply Soft. I don’t care for Wool-ease because although the colors are nice and it’s fairly inexpensive, it doesn’t hold up well, at least not in my experience. I made a patchwork blanket out of it, and some of the squares started pilling before I even finished knitting them.
I haven’t knit with Vanna’s Choice, but I’ve fondled it in the craft store, and it’s pretty soft for acrylic. I just started making a sweater with Bernat Satin, and I like it. It’s pretty soft.
