CL Sorc and mana aspect

For a CL Sorc using shock and ice damage, is the elemental aquity aspect or recharging better for mana regen?

Elemental acuity. I don’t have a starless yet. It works fine. I have crit, AS and LH on it. Lum rune if still needed. LH to restore resource is mandatory on focus if using azurewrath.
