I read comments and articles all the time about the quality of Google's search dropping. I haven't noticed it much in practice, but I'm persistent, use copious ad blocking, and my Google-fu is strong, so I usually find what I'm looking for.
Image search is another story. I've been less and less satisfied with Google Image search results, and visual search has been totally neutered. It only returns low res results that rarely match the original as well as it used to. I used to be able to plug in a 400x400 image and find a dozen copies of it at a usable size. No more. Too many copyright complaints, I assume. I've started using Bing for image and visual search now. It's not as good as old Google Images, but marginally better in some cases than the current iteration.
