The results are slightly different but where they overlap the summary/preview/description doesn't seem radically different to me. But I'm not familiar with the subject so maybe I'm not seeing it the way you do. Bing has more images/thumbnails from some of the results so maybe that's it?

For this case, the biggest tell of quality is the existence of a block diagram, schematic, or equations.

But, even without images, the "explore further" recommendations are fantastic, with direct links to research papers. Google seems to not recommend research papers (zero on my results).

Wow. For me the difference is night and day. On my phone, google gives me first two screenfuls of ads, then about the same amount of homepages of companies apparently selling mems sensors, and then some kind of wiki that seems to answer the question, maybe… Bing, otoh, has an explanation of what a mems sensor is and how it works as the first thing on the page. I guess I’ll try switching default search engine now. (For me, google results have definitely been getting way, way worse for a couple of years. At the moment, google search plainly _does not work_ for me probably 5-10% of the time, i.e. I _only_ get ads and unrelated results.)
