What it generates you have control of. So you can say "I want uppercase, lowercase, numbers, characters, of length X". So the guidelines are still relevant. The only thing you should remember is the password into your password manager, and if you want to add more words, by all means; I just find it quicker to type, no harder to remember, while making a dictionary attack unfeasible, by adding a character or two to the passphrase. I.e., "correct!horsebattery,staple" (though I agree that at four words you're fine anyway; I'm just saying that with a little noise thrown in I can type two or three words, plus a couple standalone, easy to remember characters for the same level of complexity)
