Which of the two Thief dagger classes now feels better to play?

Shadowers use different attack combos at different stages of funding, which means as funding increases, %ps decreases. Dual Bladers, as far as I know, use the same combo for all levels of funding. DBs also have an advantage where ranges are concerned, not to mention the secondary weapon.
Anyways, I'm just saying that I'm hesitant to compare two classes' damage based on %ps.

Considering that on ave a katara is going to be about 1/2 your daggers atk multiplying the %ps by 1.5 should get something much more comparable to shads %ps
