I have used the QD poly in two quilts and it worked well for me. It is dense and soft poly and quilted up nicely on my domestic sewing machine. It drapes well. It is not high loft, although they have one that is "poofier". I normally use QD cotton so can't compare with the other products you mentioned and I only pin baste so can't help you there. Hopefully, you go to their website for full info and ask for samples if you need to.
