I love Aurifil 50wt 2-ply for both piecing and quilting on my domestic machine. I used Mettler for years but, once I tried Aurifil, I was hooked. It's not as expensive as it seems when you figure out the yardage per spool. Very little lint compared to Mettler, plus more thread fits on the bobbin so less bobbin changing.
All of the thread color cards I have are made with the actual thread, so selecting colors is no problem.
