I have both the FBs and the BG (1.0):
*FB pros: Easier to get the inserts in & out of.
*FB Cons: Harder to get a good fit IMO with the snaps--DS has been in both M and L ones for about 8 months, and neither has ever fit him just right although they are certainly wearable.
They also seem to have poor quality-control for sizing, in that the Ms are drastically different sizes from the other Ms and the same with the Ls.
Have to buy them in each size as your child grows.
Some of my older ones (I got them secondhand) have completely lost the elastic in the legs and waist and have also lost snap power, in that the snap "do" but then 'undo' at an unexpected time later.
*BG pros: easier to get a good fit (btw, DS is 27 lb currently and no sign of growing out of them)
They seem to be easier for friends & family to manage as well, people sometimes get confused with the two rows of snaps on the FB or don't realize how tight each set needs to be. Not a huge deal but worth mentioning if anyone but you ever changes your LO.
They also seem to fold smaller for transportation, which is a plus when going out for the day with a dipe bag full of CDs.
*BG cons: DS can get the tabs undone and diaper off.
Mine are the 1.0, so not supposed to be washed in hot and I don't know about the dryer...? But I have used both on them and there is significant fading of the colors.
As far as washing, I have slight stains on both my FBs and BG, but I also don't line dry in the sun, so that might have more to do with it than the brand? I don't worry about stains, I mean they're diapers, right?
The final word is that though I will be using either flats or fitteds with covers/wraps for New Baby, I WILL be buying some AIO-type diapers for when we are out (which we are often)--and after using both, I'm going to be buying more BGs (I only have 2 at the moment)--not the FBs.
