If all my diapers were washed, dried and stuffed, the first ones I go for are the Happy Heiny's. Why? I have a chunky money! 17 lbs at 4 1/2 months and lots of rolls. The elastic is gently and they are easier to stuff than other diapers. I use aplix at night just because I'm half asleep when I change her.
The Wahmies are a good fit as well with plenty of adjustments available. The new Wahmies are a more generous fit than the older version. With our 2nd oldest daughter we primarily used Wahmies but she was a much smaller baby and was on the slender side. I do find that the new lining on the new Wahmies takes longer to dry and if you hand dry it is a bit crunchy. I do feel that the PUL is very good quality.
Right now we are not using the Rocky Mountain diapers. The elastic is very tight on her and it is a very slender fit. Hopefully after she is moving around on her own and slims out, they'll fit better.
I gave up on the Bum Genius. They really are a "go to" brand for a lot of parents but I didn't like the inside lining.
Knickernappies are another favorite of mine. Their elastic is super nice and the diaper has a generous fit. They are easy to stuff and of high quality. These are pricier than other diapers but it is well worth it.
