I hopped on board the duck duckgo train a short while ago ( 6 months ). I've had no real issues with it except for one thing. If some event occurs and gains popularity very quickly ( within the span of a couple days ), it doesn't really show up at the forefront of the search results.
A decent example is when I was looking up the Willy's Chocolate Factory event fiasco. I was specifically looking for images from the event to forward to my brother bc that entire event was hilarious. I had trouble with ducksuckgo. I fell back to Google image search for more ease of use.
No doubt. It's not much of a complaint, but rather an advisory. I still main duckduckgo of for no other reason than to avoid the mounting ads on Google
