The Sizzix Big Shot Pro can be used with almost every die on the market. The only ones that don't fit are the biggest Studio dies. The Studio can be used with every die. The Go can only be used with Go dies. The advantage of the Go is the low price and the small size and portability. To me it was harder to crank. The Big Shot Pro is huge and heavy and needs a dedicated space, but it's easier to crank. I don't know anything about the Studio.
