I like the Mono Poly best, and I have tried several types/brands. Mono Poly gives me less issues than the others. But I have Sulky nylon in my sewing machine now, and it doesn't really feel bad. It just tightens up every so often, I have to keep an eye on it.
I only use whatever brand of monofilament thread on top, never in the bobbin. That has never worked out well for me.
(I have never had issues with any of them melting, I do keep my iron the highest setting, but maybe it's not as hot as those who have the issue.)
I have used it in newer and older machines, by the way.
