Other Games Plants V Zombies: Garden Warfare - Who are smarter?

My dad asked me this question and it got me thinking. I want to hear what you think even you don't have the game.

Plants and Zombies are fairly smart in this game. Zombies can shoot guns which they are not able to do. Furthermore, they can even throw things, plant things and even has a scientist/medic on their team which have op gadgets like teleporting.

Whereas plants have different forms such as plasma and all those kind of forms making them a little bit harder to beat. They have unique abilities and different forms... snore ZZZZZZZ

What do you guys think?
