I've been using Superior's needles for several years and never have the problems others have complained about on the board such as quilting with batik piecing on the top and batik as the backing.
The #90 topstitch needle goes through the quilt sandwich like a hot knife through butter. When I do decorative stitching with Rainbows and Bottom Line in the bobbin, the stitching is absolutely beautiful.
I love Superior's thread and their needles!
