Otherwise, Cure II is more mana efficient and more time efficient, so SS is only worth it if you're near full HP and there's nothing more important to do, or a big incoming hit is going to mean you need SS.
Except Stoneskin as a buff adds only 70 enmity, regardless of how much HP it actually protects; e.g., a Stoneskin for 1,000HP would give you 70 enmity while a Cure for 1,000HP would give you 500 enmity. That sounds worth it to me.
