Holy of Righteousness vs. True Law of Pure Good

[Kindoki]

I am hoping some number crunchers can confirm this for me:

I have a +4 Holy Longsword of Righteousness and +3 Holy Longsword of Righteousness. I also have a +5 True Law Longsword of Pure Good and a +4 True Law Longsword of Pure Good.

I am a TWF Tempest build, and I am trying to decide with set will have better DPS in general. I don't want to carry them both around, nor do I want to have to run around switching weapons all the time. I have a set of shock/fire longswords for when the mob is not evil.

They both seem pretty close, but I am guessing that the holy/righteousness will affect significantly more mobs than true law/pure good, though the true law set would do a smidge more damage to mobs it fully affects.

Can anyone give me a definitive, numeric, answer?

Use the holy.

True Law + pure good =2d6 against 2/3 of evil mobs
Holy+righteousness=2d6+2 against all evil mobs

And the righteousness adds +2 attack

There's no real numbers to work out since it's just a straight comparison. Your TL/PG is already one point behind when each are used against the proper alignments and you already have a weapon for non-evil mobs.

+4 Holy/Righteous vs evil = +6 +2d6
+5 TL/PG vs non-evil+non-lawful = +5 +2d6
