Yandex reverse image search is currently the only useful reverse image search left that can do fuzzy matching. Like if I reverse image search a picture of a cathedral I took, it'll find other pictures of the same cathedral, even taken from different angles. Google and Bing used to be great, Google's is terrible when you include a human subject in the picture, and Bing is very very inconsistent. I have had times where I reverse image a picture and Bing finds nothing except ones a little bigger in dimension, but then I search using one of the bigger ones and it finds similar pictures like expected. It's literally the same picture, just cropped less, no color filters or watermarks.
