Well I love both since they are so different. The Flip is not a traditional prefold so it really only works as a trifold insert. It's OS so can be used from about 10-12 lbs to PLing. GMD are sized cotton twill prefolds so I can wrap them and pin/snappi/boingo them or trifold. Love GMD but the absorbancy is not even close to equivalent. Flip organics are SO thirsty. I have been able to use them as a very reliable night diaper for all 3 of my children. I certainly can't use one GMD for nights but with a couple doublers it might work. They both have a place in my stash and serve different purposes.
