Feels a bit silly to ask such an anecdotal question to somebody I don't know, but is it really better than Google? If you don't consider all the privacy yadda-yadda issues. I mean more like the size of the index, how quickly it updates things, how good is it at actual
searching (like finding an
almost exact quote which happens to exist on only one obscure site on the internet), stuff like that. I could also mention stuff like blacklisting doorways, but honestly it's less interesting, and I totally believe that it does it better than Google.
Personally, I use DDG on the daily basis, and it's mostly ok, but very-very far from perfect. More so, at least once in several days I have to switch to Google, because it is seriously better at updating the index, and DDG often fails to find something on some obscure forum, even if I know it's there (because I was a part of discussion myself!) and try to assist it with finding it as much as I can. Also, Google is immensely better at knowing local shops and finding products.
Also, Google search, being bad as it is, it still the only thing I find usable on mobile. First off, it's faster, it is integrated nicely into Pixel UI, and it's somewhat good at all these "more than just a search" type of things, like converting a timezone for me, showing wikipedia summary, flight schedule, etc. Also, integration with Google Maps, working hours and venue locations, it is actually far more reliable than, say, Tripadvisor.
Still, I feel reluctant to vendor-locking myself into payed service unless it's actually far better than everything else and can replace DDG and Google completely.
