I love them all (including the old timey Susan Bates aluminum) with the exception of plastic. I don't like plastic needles one bit. Not wild about Knit Picks Zephyr's either. (acrylic) Not wild about Denise interchangeables either (plastic-like)
But I'm saying this from my own perspective. Not dissing the acrylic and plastic needles themselves.
For me, they are not delightful to work with.
