I'm knitting the burridge lake afghan with the Comfy right now. I bought 35 skeins of it in color ivory. I've never used cotton ease or main line so I don't have anything to compare it to. I bought it because it's machine washable and a lighter fiber than wool (summer wedding present).
I like the yarn itself. It has great stitch definition and it's soft. My only complaint would be that it's a little bit fuzzy. The fuzzy/linty-ness of the yarn isn't too bad since it's for a blanket. I'm hoping it will be better once it goes through the wash. But, I've knit with pima cotton before and pima tends to be linty and fuzzy in general.
