I think that it should be pretty clear that the best weapons are going to be the elemental ones. The way they negate enemy armor puts them far ahead of non-elemental weapons.
In act 3 there are no more Electric immune enemies. Also you run into a lot of Demons and Shades. I run primarily Glandivalis for this reason. (received for free from Hybris)
I would of course bring along Edge of Night for spirit-weak enemies, (aka Templar and Orsino) but the sheer amount of spirit-immune enemies in act 3 is very off-putting.
About Saartereth:
While Saartereth is easier to get, I hate how few enemies are fire-weak how many are fire immune. It's only worth running it over Glandivalis against the Kirkwall Gangs and Hybris (and you don't have a choice in this case)
It does however, have an advantage in the sheer amount of +fire accessories you can get. Along with what Mr. afk suggested, there is the sword itself, Volcanic Shield, and ~30% worth of acessories. You can reach something like +110% fire damage. The problem with that is that you have used Crit gear for most of your slots so this is not nearly as good a benefit.
