I would say hands down allagan geared ACN beats SMN.

Mostly because Energy Drain is also potential DPS gain because of mana, Aero is a much, much better spell than Ruin II, and BFB and IR are great cooldowns.

Furthermore, and (not sure if this is even possibly relevant), possibly earth shield is useful...?

Jobs are horribly, horribly designed atm.

Also i can't remember, but can ACN get a filler thats better than ruin? I think the answer is no but I can't remember off the top of my head.
