Obviously, I like the kitchen-sink approach of MD too. :-)

If you have a series of milters and one breaks, then mail stops flowing
anyway (if you've used the F=T flag.)  More milters are *more* opportunity
for things to break.

That difficulty is a consequence of Milter itself, not of whether you
use one milter or several milters.  Many people use a combination of
milter to analyze the message and leave a header in it, and procmail
to do per-user disposition of the mail based on the header.  Our
commercial products are a little cleverer and manage to do per-user
settings without relying on a local delivery agent.
