I have tried lots of threads (not expensive ones) but found all my machines like Connecting Threads just fine. It is a bit linty, but I just clean out the bobbin area after each sewing session. With CT I can afford to have a wide range of colors at a decent price! Most of my machines are vintage, so they are easy for me to break down and clean myself. My modern machines go to the shop periodically for cleaning. So far, no issues caused by thread lint.
