I have used coats and clark since I learned to sew in home ec, never had a problem with the clothes falling apart or my quilt seams opening up. I have used expensive threads and have had issues with some so if my machine doesn’t have a problem with it I use it! Actually I was very sad that a thread I bought from Superior did something I had never seen before it is a three ply and separated as it went through my machine? I had to unpick all the stitches I had quilted and then changed thread. So personally I don’t think price necessarily means better.
