I find Yandex to be useful for some topics, but not great at others, similar to Bing and Google.

Yandex is good for escaping Western imperial news and for piracy.

Google is better for scientific research (not in general, just compared to these other two sites and definitely worse than the sites directly meant to search for publications).

Bing is...just different from Google. I guess it's easier to escape the sponsored posts.
