Doubleclick or Adsense?

I want to put ads onto my site; I was going to become a Microsoft Publisher but their program is currently closed. I was wondering should I use Doubleclick and Adsense at the same time or is one better to use than the other?

I really need an answer to this question thanks! :slight_smile:

Doubleclick is owned by Google but is not really an ad network, but rather an ad serving platform for websites.

You can use adsense either standalone or within Doubleclick.
