You mean beside free versus pay? If you go with Exchange 2000, don't use it's native certs, as they are only x.509v1 not the industry standard of x.509v3. Instead use the also free Win2k CA and integrate. More work, but better results and if you ever want to secure email between companies it becomes possible.
Enterprise PGP is neither free nor supported out of the box. PGP is also regarded more as a user to user solution, where trust is implicit rather than explicitly structured, unlike with S/MIME. Enterprise PGP solves some of that, but if you need to do secure mail with another company, it will only work if they also bought Enterprise PGP. S/MIME will work with any vendor's CA, Baltimore, RSA, Entrust, Verisign, Sun, Microsoft or even open SSL.
