DT joints are stronger than box joints. They will hold with out glue, not
permanently of course. A big advantag of the DT over the bok joint is that
on many of the better jigs you can adjust spacing and the tails and pins to
fit the project. Bokjoints dictate that the project be designed around the
joint length.

It's true that dovetails will hold without glue.

However, box joints can be can be cut to any finger width desired if you
have the right jig.

Also, box joints can be made as strong as or stronger than dovetail
joints because you can easily cut narrower fingers thus providing more
glue surface. (See http://woodgears.ca/dovetail/index.html for one test
of this.)
