Except not quite.
Benediction is basically idiot-proof. If a WHM uses Benediction, there's no way that anyone can mess up its effect. Once used, it's done, and that's that.
CC requires coordination. It requires mobs to not be taking damage. It requires AoE to be stopped completely, or it is ruined. It requires the group to anticipate its use and count on it. If you AoE sleep and the SMN or MNK doesn't get the memo, you've wasted a GCD
CC moves can be useful, but they require more coordination than you'll typically find in DF groups or the open world at present.
