There really isn't a "best." It all depends on what you want to do. I have the AccuQuilt Studio 2, and all I have or ever want are the strip dies. That works best for me. If I wanted, I could buy and use any of the dies for the other AccuQuilt cutters. The Studio 2 is heavy, and the dies for it are heavy, so it is not portable and would not be a good choice for everyone. The electric AccuQuilt is a better fit for those who have limited arm motion, and the smaller Go! machines are more portable. With any of the AccuQuilt machines, you buy your dies; you don't design your own. For that you need a different type of machine, such as the Cricut.
