Well, this is obviously just my personal option, but:
sendmail - No longer the security nightmare it used to be, but it is
the slower of the bunch.
postfix - The easiest to configure. Has enough features and speed
to keep most people happy.
exim - Fast and powerful. Lots of features and highly configurable.
But ONLY if you know very well what you are going. Not as
hard as sendmail to configure (think sendmail.cf), but
much harder than postfix. Expecially recomended for people
(like me) that enjoy micromanaging and customizing every
small detail. ACL features are a god given.
qmail - (Take with a grain of salt, since I dislike dbj) A pain.
It is fast and secure, as long as you use the stock
package. But you will need to include several external
packages to get even basic functionality, and everything
about it (except SMTP protocol itself) is non standard,
and the configuration is spread between a lot of files
and directories. But it really is fast (slightly faster
than exim in some cases, about the same in others).
As you can see, I use Exim so, again, take another grain of salt.
My current exim setup is, as far as I know, impossible to reproduce
with any other MTA, unless you use several external hacks (multiple
instances with different configurations, with port redirection, to
name just one).
But most of the time, when recomending a MTA to others, I say
postfix.
