Many people use polyester thread for quilting every day. Especially longarm Quilters.
If the thread is strong enough to not break with a tug test, and your machine likes it you can use it to quilt.

And in reference to your question— personally I would choose the Aurifil if you decide to go that route. I use a Lot of Aurifil thread and love it. — cotton, polyester and invisible thread from Aurifil. I have a longarm so I only use the cotton for Piecing, not for quilting— cotton breaks too easily with the high speed machine. Polyester is much stronger.
