Personally, in pemail, I chose Mail::POP3Client over Net::POP3 because Mail::POP3Client offered more methods for accessing the pop3 server, specifically the Head(MESSAGE_NUMBER), Body(MESSAGE_NUMBER), and HeadAndBody(MESSAGE_NUMBER [, PREVIEW_LINES]) methods. They allowed easy access to parts of the message that you wanted without necessarily grabbing the entire message. Other than that and a few very minor differences in setting up the server connection, they are very similar and I say use whichever you prefer as they essentially provide the same functionality. I just overall found Mail::POP3Client a bit easier to work with for a Perl neophyte. :)
