In Divinity Unleashed, is dual wielding strictly better than 2h/staff for Sparking Swings build?

Don't see a lot of discussion about balance in this mod, but figured i'd ask anyway.

I see a lot of discussion for a Master of Sparks Sparking Swings build on dual wielding 1h weapons vs a 2h staff, with pros and cons for both but the edge seems to lean towards the staff.

In divinity unleashed, where hybrid builds are much more viable and splitting damage types isn't bad, is dual wield just strictly better? Should I not even use the Divine Spark axe in Arx? I purely care about more sparks now yeah?
