I will not repeat all the info about each diaper; please read the reviews for all the nitty gritty. This post is simply to point out differences!
Both have serged edges at the waist elastic, but the Sbish has turned & topstitched leg elastic.
Both have nice, long wings, though the diapers have a slightly different shape.
The ODC is larger overall, though the Sbish stretches to nearly the same size.
The Sbish does seem to be cut a bit trimmer through the middle.
The Sbish comes with two, 3-layer, lay in soakers, while the ODC has a single, 4-layer bamboo-terry soaker, that snaps in, and is sewn in layers for faster drying. It is essentially the same length as the diaper, and can easily be doubled over in the wet zone.
Both worked well with Boingos and Snappis.
Both diapers are pictured on my son at the same age/weight (around 9.5 months and 16 lbs.) Both fit with lots of room to grow.
I haven’t done any pseudo-scientific absorbency testing, but both were plenty absorbent for extended daytime use for us. Each has its own features, so if you’re trying to choose, decide what cut/shape and what soaker style you prefer most!
Both diapers were received at no cost for review purposes. All opinions are solely mine.
