One other observation, is that the mettler seems to be thicker and stiffer. Even though I always buy 50 weight, the mettler feels thicker, and I seem to have more issues with thread breaking while FMQ (full disclosure, that could be, and probably is, user error).
If it helps, I have a bernina record 930.[/QUOTE]
I have both, and the Mettler 50 is much thicker. The Aurifil breaks much more easily (when snapped), so I've only used it for satin stitching so far. It looks exactly like Mettler 60-weight when satin-stitched.
I am not sure if thinner is better when piecing, in terms of sturdiness, so for that reason, plus the price, I have stayed with the Mettler. I guess I'm secretly hoping that another thread will become the next big thing, and then all those gorgeous spools of Aurifil will become more affordable.
hugs,
Charlotte
