For questing/soloing or tanking?
Previously, I was fond of faster weapons as a Horde Paladin since Seal of Righteousness was the mainstay. With the recent changes to Seal/Judgment mechanics, the seals themselves, and certain abilities being based off of the raw DPS of the weapon... I haven't made up my mind yet.
So far I'm still leaning in the "slightly quicker" direction, but I tend to like to make a pretty detailed evaluation of things like this (where experimenting is pretty easy and its not vital to know right away) before making up my mind.
Sorry it's not more specific. Best I can say is... try things out, get used to the changes and find what works better for what you're doing.
