Agreed 100%.
Why do you guys say that the Islam is the worst religion of this game? I mean, in game terms. Cheaper units and more growth guarantee excellent cities with unbelievable power. Combined with +2 stability on conquest, your empire is basically set in stone. Really, I think Catholicism is, if not by far, the worst religion now. Diplomatic relations are a laugh since all Catholics want to trade with you anyway, so the only benefit would be gifts from the Pope, which is only useful before 1000 AD. Yes, the same thing can be said for units (who needs 1 hammer Musketmen?), but the growth modifier is a serious power combined with the Hansaetic League. Orthodoxy gives more stability but not much, same thing could be said for the maintenance cut.
