As someone who doesn't have a whole lot of $$$ to spend on expensive yarns, I have used Bernat quite a bit and have found them to be quite good actually. I have used Denimstyle (I thought it was 100% acrylic??....oooh, just checked, it is
a cotton blend!), CottonTots, Solo, Softee Chunky, Berella, and Sox, and have really had no problems with any of them. I personally kinda like acrylic and I'm not ashamed to admit it!!!!!
I have also used a few of their free patterns from the website and have really enjoyed them.
