Diceware

I think that diceware is better.  With this other method there are only 65
distinct sylables to choose from.

A 5-word diceware passphrase like "crust cord cliche gemma thea"
provides better security than a 10-sylable privaria password like
"gezugegekelagegogiro"

Personally, I think that "crust cord cliche gemma thea" is easier to
remember than "gezugegekelagegogiro".
