Also, another important difference: if the domain has child zones,
grandchild zones, etc. with "stub" you'll be sending queries directly to
the nameservers for the appropriate level of the hierarchy; with
forwarding, everything is still forced through the same set of
forwarders. This may or may not be a good thing -- e.g. you might not be
able to *reach* the nameservers for the descendant zones directly -- but
generally speaking, with an open (inter)network, it's more efficient to
"skip" levels of the delegation hierarchy, and to have more diversity in
the nameservers you talk to. So "stub" usually wins out here.
