My DH bought out a closing store's supply of good quality cotton wrapped poly thread, including their large thread rack. I liked it just fine, but my sewing machine expert said it was linting more than it should. I found he was right, so stopped using them. Mainly, I use Signature threads, which work pretty well for me. Aurifil is somewhat better, but MUCH more expensive. I also prefer to use the large cones so I am not always changing threads. I detest Star threads.
I suggest you try out what is readily availible to you and make up your own mind.
