We got the Go for the quilt shop where I work. It didn't cut very well for our use, so we sent it back and got the Studio. It really cut a lot better. I also have the Studio and the Go (regular) at home, and I got the adapter so I could use my Go dies on my Studio.
The thing I wish I could do is to buy dies with several of the same shape on a single board. Like one that has 8 5-inch squares, so I could cut 8 X 8 layers = 64 squares with one pass. It takes just as long to cut by rotary cutter as it does with a single shape on a die.
