I also very happily use it for quilting as well. I never seem to have tension issues if Aurifil is in the machine.
I've acquired a few spools of Superior threads, and been quite pleased with how nicely they quilt with as well. Superior usually has a deal where you can get a sample pack of threads for a discounted price, as long as they choose the colors. I have used their Bottom Line threads in my machine and in a long arm, and loved them!
Oh, and don't be cheap about your thread. Pay attention to how much you're actually getting on a spool, and consider your frustration in the long run with inferior quality threads.
