Aurifil, Gutermann, Metler, or Essentials from Connecting Threads. Coats and Clark left North Carolina for overseas production years ago, and their quality has gone downhill ever since - thick and thin spots, easily tangling and knotting, breakage, and overall bad compared to other threads. (Their factory remains empty and an eyesore). I find most Coats and Clarks users who still like it haven't tried enough other brands to make a good comparison. Some years ago I gathered up all my C&C thread and donated it to a thrift store.
