Spybot or Adwcleaner? What is the best free anti-malware, and why?

I find the best to be Malwarebytes. I've never had a problem with it, which is more than I can say for everything else.
The free version is usually good enough to keep you your system. Especially if you have an adblocker installed. And the paid version adds an extra (but rather unneeded) layer of protection.
