Off the top of my head:
CATHOLICS have the Pope who is supposed to be infallible when he speaks ex-cathedra in matters of faith and doctrine
Orthodox don’t have this position.
Orthodox priests are allowed to marry and have families. Not so Catholic priests.
Orthodox were persecuted by Russian Communists.
The Catholic pope let Chinese Communists pick their bishops.
No, that's not correct. The Orthodox ordain married men to the parish priesthood. That's different from "allowing priests to marry". Once an Orthodox priest is ordained, he cannot remarry and remain an active priest, even if his wife dies.
Orthodox bishops are all celibate; they are typically recruited from monasteries.
Western (Latin Rite) Catholics traditionally have not ordained married men to the priesthood. Eastern (Byzantine Rite) Catholics do, just like the Orthodox, although not typically in the US (for political reasons).
