If it does was you need it to do you should definitely use it, privacy vise it's obviously way better than google. Haven't tried in in about 2 years, maybe the search results got better but the last time I tried it often presented me weird sites that technically contained the words I searched for but were completely irrelevant - entered the same question onto Google and immediately got me a stack overflow question that was practically the same question I had but phrased a bit differently. But as I said, maybe it's no longer so bad as when I tried it.
