I have both GO and Sizzix....Sizzix is easier to crank, but each has its place. As far as gfg...I did buy the go die that had two cuts..one for fabric, one for paper...I found seam allowance to skimpy...so paperpieces.com has a template that offered an acrylic with 3/8" seam allowance(for fabric), and fiskar had a handpunch the size I needed for papers....so I'm doing my gfg with those tools. But, for other projects...can't beat the die cutters!
my FYI...on some Sizzix dies-squares, rect.,tri., it will state -inches-" assembled, that is not the same as "finished" as the Accuquilt dies state.....
