My last experience with bings reverse image search was in 2022 or so, so no vouches for its quality these days. I’ve had mixed results with tineye, but there was another one which I don’t even remember the name of that generated reverse search links for all the search engines, I think it even listed that Chinese one and a few others I’ve never heard of rather than being its own thing. I had decent luck with that, I found Bing still worked the best but I haven’t tried it since
Google lens definitely wins for object search though. Not the point of the post, I know, but it’s kind of funny how their reverse image search is dogshit but their object recognition is flawless
