I have both GO and Big Shot......the GO has more choices of dies, but also more expensive. The big shot (Sizzix) can cut x8 layers, but I don't push either to their max...I usually keep max at 4 layers for both. I like both machines...have way more GO dies...but as far as generic geometric shapes.....cheaper at Sizzix...if it's the size you want....BUT...now I notice even Sizzix prices are going up a bit. You also have to order direct from Sizzix....at least I do...there was a short time that Hobby lobby carried but no more....
