It's still unmatched in finding programming solutions. Compared to DDG, which is my daily driver search engine, Google is able to get into Github issues, Stack questions, etc much easier than DDG. I'm heavily using !g in most of my programming questions via DDG.
I find this partly true, but I still only need to use Google over DDG maybe 20% of the time, and when I do it’s usually because I’m desperate (and even then, I rarely find what I’m looking for, or what I think I’m looking for). I find Google’s grouping together SO pages to be particularly useful, but most of the time when I’m looking for doco or the first few results, DDG is at least more than adequate.
