Sorry I don't know anything about the brands you named, I just wanted to let you know that Handiquilter has released a new product that is a sit-down machine set into a height-adjustable stand-up desk. That means you can quilt sitting down, standing up, or anywhere in between. I have no personal recommendations, I saw it on Bethanne Nemesh's FB page, White Arbor Quilting. She posted a short video demonstrating it if you were curious about it.
