Spell Power vs Spell Lore

[Amroth]

In the new (U32) crafting system, I can have the following choices. Which would be better, and why?

NOTE: I run as a Art(1)/Loc(9)/xxxx(10), with GOO and Utterdark.

EQUIPMENT   PREFIX      SUFFIX          EXTRA(ML10)
=========   ======      ======          ===========
Glove       ~~~~        Potency         ~~~~
Weapon 1    Corrosion   INS Corrosion   (open)
Weapon 2    Radiance    INS Radiance    (open)

        == VS ==

Glove       ~~~~        Spell Lore      ~~~~
Weapon 1    Corrosion   Acid Lore       (open)
Weapon 2    Radiance    Radiance Lore   (open)

At Level 20, I'd have:

        Power   Critical
        =====   ========
Acid    111+73  -0-
Light   111+73  -0-

        == VS ==

Acid    111     16+8
Light   111     16+8

Additionally I'd of course have Spellsight, Evocation Focus, and Spell Focus Mastery on other equipment.
