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?
