I know several longarm people. Most of them seem to use either SoFine or Glide. I do have some of each but honestly, I haven't used my Glide yet. I did try it and it stitches nicely. Glide is a bit shinier and SoFine has a more mat finish. One slight problem I found with Glide is that I have to make more tiny stitches to start and end as the stitches pull out a bit easier. Not a biggy!
