What is the recommended variant of PGP.

Although I (naturally biased) prefer to use Cypto Kng, I recently needed to use pgp, so I decided to upgrade. I went to PGP.com. Their freeware PGP is fourteen megabytes of mystery code. Something that big and mysterious does not make me feel secure. My current pgp.exe is 250K, for which I have source code, source code that I have looked at. The program performs functions that I understand, in ways that I understand. What is the recommended PGP?
