why not always maximize clicks?

Hey all, I'm new here, and to adwords in general.

So regarding Flexible bid strategies, I have a question.

Unless you are advertising for branding purposes, what is the point of using any option but "Maximize Clicks"? "Search Page Location" is nice, but at the end of the day, we are here for clicks are we not? So if "Maximize Clicks" gets the most clicks, why use anything else?
