I think the econobum prefolds are so soft. I like them.
But you asked about gmds.I have gmd orange and they still work fine trifolded on my 4-1/2 mo. If you want gmd's on a budget thpugh then reds are the way to go.
You can find preemie prefolds cheap. I used those for the first few weeks when they are so tiny.
