Well, I do like the Sandy's - but they are only good for daytime use. They are not absorbent enough for overnight.
Our favorites - the two we have purchased in mass quantities.
BG 3.0 - they are great, my only concern is that we have a big girl, we are already on the second snap and she is four months old - are they really going to last until she is toilet trained? We had to do away with the newborn inserts - just not enough for our super soaker - but the larger inserts they come with are doing the job - and you can throw the newborn one in for overnight use.
Fuzzi Bunz are the other front runner - I love that they snap - this doesn't catch on clothing the way velcro does. The con is that they are sized. But we have purchased a bunch of mediums which are just starting to fit - as she is only approaching 16 pounds - they are great double stuffed for overnight. And the smalls still fit and show no signs of being too small.
I think I might want to try one or two more types though - just to see. But, I think that those two will remain my favorites.
