ZCash is controlled by a privately-owned company in the U.S., who gave themselves founder's rewards.
It's also designed in a way to allow "poison pills" - i.e. those in control can force a single transaction on a block, thus giving a vector to deanonymize someone.
You may ask, "Who would do something like that?" and the answer would be the U.S. government who can compel privately owned organizations via secret court subpoenas. Monero is more private than ZCash, and has a record of not acting on self-interests.
