I have the Go, the Go Baby, and the Go Big. I won the Go Baby, bought the Go and got the Go Big as a gift. I rarely use my rotary cutter anymore. I don't have the studio because it takes up a lot of room but I sure would take one if it was available to get for free. There are many more dies for the studio then the Go and a lot for sewing other then quilting, like totes, bags, aprons, etc.
