I’ll go first. I’ve used a lot of search engines, I used duckduckgo for quite some time but found their search results kinda bad. I’m currently using ecosia the search results are similar to ddg’s but at least I’m planting trees, so there’s that.
duckduckgo primarily, but have been starting to dabble with a self hosted Whoogle.
Most small search engines use bing results which are a hit or miss compared to Google.
Startpage is the only privacy focused one I found that uses Google search results. The UI is fine for the most part, except the image search maybe.

For the moment I am using brave search not on brave browser but as a firefox add-on, a fine tuned searx.be and perplexity.ai, which isnt a search engine but a connected chatgpt ai with links in the answers.
