DuckDuckGo > Google BUT...

If you are using DuckDuckGo because you don't like Google tracking you, you are probably doing it wrong. You can still be tracked unless you follow the guidance in this video. 

Now if you are simply trying to not do business with Google because they are part of the evil empire / progressivist problem, then that probably doesn't matter as much to you.  But it should matter.  DuckDuckGo is doing their part to help you and you only have to make one small change.  It's worth it and you are also making life harder for Google.  Use the DuckDuckGo extension.

To Liron Segev's last point about Google having better search results, I have found this to be true for some searches, but to be fair Google has roughly two decades of head start on DuckDuckGo.  They are also data mining your browsing data to improve their results.  It's a trade-off.  DuckDuckGo will improve over time but may never match Google because of their value proposition (privacy).  I've learned to use both where appropriate and default to DuckDuckGo as much as possible.
