bumGenius One-Size diapers - almost exclusively. While we were happy with the overall performance of the BGs, we wanted to try a different brand with our son. I had heard about FuzziBunz and how fantastic they were. So - we ordered a good supply of size small FuzziBunz Perfect Size diapers. I also had one FuzziBunz One-Size diaper to try.
I was really surprised when comparing the two. When I had read about the diapers, the Perfect Size diapers promised a more trim fit than the One-Size. However, when using the diapers, I found quite the opposite to be true. The Perfect Sized diapers seemed a little more bulky to me than the One-Size FuzziBunz. I found the One-Size to be very trim on our chubby baby. When he outgrew the size small FB, we switched to the medium sized FBs. I noticed the very same thing. The Perfect Sized medium diapers were much more bulky than the One-Size FuzziBunz.
The other differences aren't as pronounced - but present nonetheless. I find with the Perfect Size (PS) diapers, I get more leaks during bedtime use. The OS diapers seem to be a better fit, overall - with fewer leaks.
As for ease of use - both diapers bode well. But the Perfect Sized diapers are a bit easier - since I don't have to adjust the elastic in the legs. The One-Size (OS) diaper is much more durable. When we used the PS size small, a couple of them didn't hold up well and the PUL started to wear out here and there. The OS diaper that we have seems to be made of higher quality materials all together.
As for the inserts - I can use almost any type/size of insert with the PS diapers. Alternately, the OS diapers seem to only fit the FB inserts that came with them. That is a bit annoying when I'm in a hurry and just want to grab a diaper and an insert on the run.
Both diapers are great. I like using FuzziBunz well enough. I think the diapers are just as good - if not better - than the bumGenius line. They are soft against my baby's skin, the colors are pretty, they wash well, they are easy on the planet and equally easy on the wallet. No matter the size, FuzziBunz diapers are definitely good diapers.
