it's honestly getting a little difficult to tell, because there are quite a few high capacity diapers available now. There are numerous varieties of the comficare design, and they have differnet cores, different liners, and different shells. The shell and padding shapes, elastics, and tapes seem to be the main consistent things. But with the others changing, core composition and top sheet in particular, they can get hard to compare. Is a diaper higher capacity even if it has poor wicking and tends to leak before full?
But yes I think most will agree with the general opinion that the comficare design diapers are the current kings of capacity.
