I havent been able to find a reputable source for your claims regarding those two popes. Remember, Protestants and Anti-Catholics invented many tales about the papacy (i.e. Pope Joan).
There have been many many holy and great popes. A few that come to mind are Peter, Clement, Pius I, Fabian I, Leo IX, Pius V, Pius IX, Leo XIII, Pius X, Benedict XV, Pius XI, Pius XII, John XXIII, Paul VI, the two John Paul's, and the Pope Emeritus Benedict XVI.
