I'm not familiar with either YLI or the Hiroshima Tulip between -- will have to check them out sometime.
I have only used two kinds of thread for hand quilting -- Gutermann hand quilting thread and Aurifil 28 wt. The Gutermann is quite wiry, while the Aurifil is very soft. I can't say I really have a preference for one over the other, it just depends which brand has the color I want.
