Crossbow vs Bow?

I was looking to upgrade my bow and realized just how strong quivers are especially with the passive tree providing boosts to quiver bonuses. I know the crossbow has some nodes for boosting grenades but with the crossbow not getting an offhand does its scaling keep up with bows?

I know the weapons serve different purposes but they also have a lot of skills that feel similar like the poison gas arrow and gas geenade the explosive arrow and bolt ect.

Thanks for the help.
