They are less invasive on the privacy front, but they also push their products much harder down user’s throat due to less revenue from less accurate ads, just look at DDG’s frontpage.
I also found them self-censoring towards IPs from China, albeit this could be the direct result of using Bing’s search results.
It’s much easier to compare it with something like SearXNG which has the same core principle, without ads, without censorships, without invasive marketing.
I’m running it on a remote server.
