Nah, it's strictly inferior. WKZ is old standard, which means its skill gets op elecomp bonus to damage and can be boosted by another 1.5x with CIT. Ebil Knight, despite the similar skill animation, is modern spell-type skill, which means lower elecomp and no bonuses from CIT.
Ebil Knight is listed as one of the Missing Armors in the Missing Info Subs thread. You can use that for reference in case you're in doubt rather or not we have subs on a particular item.
For clarification, Ebil Knight shares the same type of Elecomp to damage as White Knight, but its a modern Offensive lean armor that treats it as a Spell type that doesn't receive the weapon's MC bonuses except for Spell boosts. A standard armor is capped at 1.85 Elecomp with 85/75 max inaccurate modifier, the quest that offers Ebil Knight's shop has a temp version for you to try out and purchase if it is to your liking.
There are two other Darkness locked Elecomp skill armors one gold priced, one Z-Token, namely Angel of Souls from Death's Domain Nowhere that uses Hp and Terror Raiment both which have Elecomp to cost instead.
