Answer:
The term Dual Federalism refers to the political system through which a federalism is established where both the Federal State and the local States divide powers and limit each other with respect to their functions, each exercising their own and without getting involved in the other's.
For its part, the term Cooperative Federalism refers to the federalist political system by which the Federal State and the local States have a differentiation in terms of their levels of performance, but not in terms of their tasks, with which they cooperate with each other to compliance with government objectives.
Personally, I believe that cooperative federalism is more effective, as both spheres of government deal with similar issues, and control each other through a co-participatory and non-restrictive regime as in the case of dual federalism.
