We actually need more words, as entropy of the words is less than characters.
Suppose there is about 50000 words (There is 301 000 main entries in OED).

Than
50000^x > 94^13 => x => 5.5

So i would say that
"balloons are very nice" < "@$XsBv2JMc473"

Also entropy of word like "are" is almost zero, so predictable.
And xkcd strip actually kind of takes this into account.

I will stick with pronounceable/memorizable passwords
like pwgen kindly generates for me.

P.S. You have typo in your passwords.
