Which Cygnus is best after Chaos?

I am leaving for my vacation on sunday and coming back the day of chaos so I don't have time to train a DW to 120 in 2 days.
Which Cygnus is best at leveling after chaos?
My Paladin has job quest "Empress's Might". I thought this was for only UA's? What does Empress's Might even do?

Strikers, hands down. Or you could opt for a SoulMaster.

Completing "Empress's Might", a.k.a "the lunar dews quest", allows you to wear gear 10 levels higher than you are.
And, much more importantly, it is a pre-requisite to getting the quests for acquiring a cygnus skill (Soul Driver, in your case) on a normal adventurer (your Paladin).

I don't find the trouble worth while. I enjoy playing Paladin without it and after Chaos it will be useless
