Many don't like the pinked edge because they don't know how to sew them together that way. I only buy Moda precuts. They are always accurate. I measure other brands accuracy before using. I have the Go and it's easy to cut a lot of charm squares 5" or 4 1/2". I seldom cut block pieces with a rotary cutter. It's pre cuts or die cuts for me. The only problem I have to deal with is perfect 1/4" seams.
