I'm using DDG for almost a year, and I'd say that DDG is slightly better because I have a bit more control. It's important when you're multilingual (common in Europe) to be able to de-localize results chose language etc.
But it isn't MUCH better. DDG is just slightly better than Google, that has become infuriating.
I use it regularly but it is getting to be unreliable for technical searches. I often have to resort to using google when trying to track down information about programming problems.
