I decided on the brand of thread I liked and that's all I buy. Too many good brands to keep up with them all. It's simplifies my life. I piece with Wonderfil and machine quilt with Omni. I use Sew Fine in the bobbin for piecing and quilting. I do have specialty thread but most from Superior or Wonderfil. I have used Glide and like it but my go to quilting thread is Omni.
