apollo-link-state in its current form is incredibly simple. I am using it in two apps right now and it fits their needs well enough. But I have another app that I would never consider using apollo-link-state in, rather it uses redux. This third app has far more complex client side state that I just can't imagine apollo-link-state handling well at all. I actually think mobx-state-tree is my favorite of them all, but I shy away from it due to its performance issues. When they solve that, I will likely adopt mobx-state-tree quite often.
