That was my experience the first time i switched but i insisted cause my hate to google prevailed. What i felt at the moment is that google had so many aid for searching that 1: it kind of de-trained me in how to properly use keywords and 2: was great for searching common stuff but made search too convergent.

This is just based on vibes and feelings, so it could very easily be a lot of nonsense.

Now trying it back, i feel it off, as I said, but it could also be that i just got acustom to how DDG works.
