It all depends on what you like. Have you had the chance to try both out? They both do the same thing, but it all depends on how the machine feels to you. Some people find the gammill heavy and some don't, and some find that the Apqs heavy and also not. It also really depends on what you are comfortable with. I have the gammill and I love it, but to my friend that also quilts she likes the A-1 machine, to her its lighter and she likes the way it quilts. I like the gammill it feels right to me when I'm quilting. I like the way quilts and the feel of it.
So I would really try them out and see what you are comfortable with. They are both great machines! Hope this helps. Lisa
