Passphrases are not more secure then regular passwords by default, the problem is that a lot of people use phrases that follow simple grammar. Capital first letters of each word, a sentence that is actually valid and no spelling mistakes make it a lot easier to crack then 50 random characters (or 20 random characters). Passphrases that work are random sequences of words that have spelling mistakes, random capitalization, aren't found in any book/song/poem and preferably mix several languages. The famous "correct horse battery staple" is better then your example, I have memorized 20 random words from 3 languages and use those words in some combination in all my passwords.
