I use Connecting Threads's thread almost exclusively. Personally, I don't find it overly fuzzy, or with a lot of slubs. I do have a simple, older machine (Singer 403A,) so maybe that's why I don't have any problems. Maybe it's too unsophisticated to, "know any better,"...LOL.
My number one, go to color is off-white/cream. I go through far more spools of that color than any other.
Have fun quilting!
