Of course SCH will beat SMN in term of utility... they're healers duh.

SCH won't be a viable dps "class" until.... never. No accuracy.

And SMN, for a DPS class has quite a few nice skills that brings utility.

I used similar gearsets to show that the gain would be equiv as gear got better (cleric stance giving +10% offsets the dif, IL70 is a great starting point since it's the stage after entry gear at 50).
When looking at the stat bonuses on IL90 MND for SCH stays the same as INT for SMN but you'll see a loss of det and acc with a gain of piety and spell speed (ex: arg gloves vs smnr gloves for example).

As for accuracy, I've ran all except coils as a SCH dps in our premades (which we all had a pretty good laugh at while doing it) and was able to hold the same to an equiv gearset SMN. in our extreme premade I didn't really notice the accuracy issue either. So by endgame for acc that pretty much means 'coils'
