I would say for personal stuff (ie, non-programming) it is. For programming, I continually have to switch back to google. DDG is way worse for me. Maybe it's just me, but the types of things I search for just don't work on DDG and I've wasted way too much of my time looking for answers using DDG, only to find them quickly with Google. It totally frustrates me, because I would much rather use DDG.
