The crit aldo is still stronger. Normal aspec bene noct stance is stronger (805>600). However when u apply a crit heal, it about 40 percent. but that number is doubled so its about 1260 potency in total where the crit noct shield is 1180.

Ultimately though, noct shields are still stronger than sch on average and all the time for aspected helios. However, its the utility and the flexibility of the SCH that puts it head and shoulders above the noct ast right now.
