"As good" is subjective. I hate search bubbling. I'd rather click through semi-relevant results a few times then figure out why google hasn't heard of the movie Django, for example.
Also, I switched to ddg years ago, and can't remember one time when I thought that personalizing the results would improve matters.
Every few months, I'll search for something, not find it, and try google. Falling back to google has helped maybe two times out of dozens of searches. In one case google found an old email thread where someone asked my question and got no answer. In the other, I was looking for a specific document with a solution to a Linux issue. I had found it with ddg before. It turns out the solution no longer worked, and was superceded by documents ddg had already returned.
It is unclear that running that test with google as the primary search engine and ddg as the secondary would have different results.
