For Attack: Excal/Bura > All Sword Combos(Slightly edges out Uson Offhand)
For Accuracy: Excal/Uson Acc > All Combos(Slightly edges out Bura Offhand)

Excluding Excalibur: Bura/Uson > Bura/Anahera > Bura/Egeking = Bura/Eminent Dagger > Bura/Other Swords.

Simplified. Egeking really doesn't serve a lot of purpose if you can get your hands on Bura, if you can't then you're unlikely to get Anahera, if you do get either of these two swords you should use Eminent Dagger and just ignore Egeking. If you don't have either Bura or Anahera though you should probably pick this up and offhand Eminent Dagger all the same. It's also worth noting that Eminent is very low on Accuracy so that's another small boon for it, take it for what you will.
