Actually, they're identical.

You'd think the bucket manufacturers would have the sense to have
the last rib on the outside be at the right place to prevent
sticking when stacked. Some of them do.

FWIW, I've had some luck separating stuck buckets by directing a
compressor air jet nozzle at the touching surfaces to try to inject
air between the buckets and pop them apart.

Seems to me that if the last rib was not a closed circle the vacuum
would never be created. Of course, that would be more expensive to
manufacture since you'd need to leave the gap(s) while making sure it
wasn't a sharp edge that would result in lawsuits.

The vacuum seal is bucket surface to bucket surface, which combines with
friction between the two wedged together surfaces. In many cases, the friction
is the bigger problem. The compressed air trick will expand the outer and
contract the inner bucket, killing two birds with one blow.
