Well, it depends. CTM is the least "expensive" method to update your
source repository because you only get the "pure" diffs. On the other
hand you must not make any changes to your source tree in order for CTM
to work.
CVSup is designed for people who are making local changes to their
sources. As this requires a more complicated update mechanism a CVSup
session requires the exchange of much more data, so CVSup is usually
more "expensive" than CTM.
So, it's finally up to you to decide what is of more importance to you.
But remember: Migrating from CTM to CVSup is simple, but there's no easy
(i.e. inexpensive) way back once you change your mind.

With the CVSup ports you only get the ports files as you normally find
them under /usr/ports. This does *not* include any distfiles from
/usr/ports/distfiles.
