My primary search engine as of now is DDG, Their results are mostly fine (and powered partly by Bing). When their results are not good enough, I ask Google; often, but not always, it's better. For some other kinds of queries, Google fares notably worse than DDG, likely because SEO tricks are disproportionately directed against Google, and not always work against other search engines as effectively.

I've had my issues with Google ever since they ran a series of ads pretending to be for Blender but actually linking to a scam site. (I’m not sure if it’s gotten better since then.) While I do occasionally come across questionable ads on Bing, they’re definitely much less frequent. For what it’s worth, I’ve switched to using Edge as my browser as well, largely because Google refuses to address one of the most frustrating issues with its external link profile behavior. Specifically, Google forces external links to open in the last-used profile, rather than letting you choose, whereas Edge allows you to customize this behavior.

On top of that, Bing’s deep search feature has proven to be genuinely useful

I wrote https://www.arnavion.dev/blog/2020-12-05-ddg-vs-google/ in 2020. The tl;dr is that Bing's (DuckDuckGo's) results were garbage and Google was giving the correct answer within the first five results.

Running those same specific queries now, the Google results are as bad or worse than Bing's results at the time, and Bing now frequently gets the results that Google did at the time. But my everyday experience is still that Google gives generally better results than Bing / DDG.

I've went through a few stints of using Bing. Eventually I end up starting all my queries with `@google`.

>Their market share is so big that no one running SEO scams is looking at their Bing results

That's pretty unsound logic for two reasons. One is that it's not very likely that SEO optimization for different mainstream search engines requires any more effort than for one, secondly Bings ~5% market share is what, tens of millions of people still? If nobody games it you're leaving free money on the floor, and internet scammers are hyper competitive.
