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.

I've tried everything and I really really really can't use Google. It just never gets me what I want. DDG works ok, and is usually my default because it's fast and simple.

Recently (1 or 2 years) I've found Brave search to be fantastic though. You may want to disable the AI search summary (it's better than Google's or DDG's ai stuff, but still ultimately ai). Now, I find myself reaching for brave search when I'm doing more serious searching. I have both DDG and Brave saved as search short cuts in librewolf. Highly recommend.
