There is a famous paper that says PGP is hard to use. I have a bit of an issue with bits of the study (bunging UNIX tools into Classic Mac apps has never been particularly usable); but there are, undoubtably, more usable tools if you need secure communication nowadays.
That said, I still like and use PGP—and it lets you do a bunch more things that Signal can't (signatures for one). If you integrate it into a mail client, many of the wrappers make it pretty easy. If you read the man pages it is no worse than other, older, command-line tools.
Give it a go. Tricky things become easier with practice. There is a manual.
