sizzix can use the go dies but not the other way round due to the thickness of dies. silhouette is a electronic cutter so there are no dies. The only qualm I have with dies is they cost a lot and only do one size so you spend a fortune and are limited. Mine collects dust to be honest and there can be fabric waste. I would say if you have a lot of money to invest in dies of different sizes go ahead but if you don't you will find it very expensive. luckily I didn't buy my machine so not a lot invested
