Better to use a protocol designed with encryption in mind, like Signal, to get forward secrecy, avoid leaking metadata, and have encryption always on by default.
UPDATE: I have been reminded that PGP does not have to be used with email. I meant to say that I used to love using PGP with email, since that is the primary way I have used it. I will not comment on the use of PGP outside of email, since I haven't carefully examined its use in other contexts.
