DuckDuckGO - Not quite as good at the actual searching as Google, but to be fair that's probably because it prioritises user privacy and doesn't track you to give you more relevant results like Google does.

Bing(?) - I only use it to get my daily Microsoft reward points, but I've heard it's better than google if you want to search for porn. But in the year 2020, who uses a search engine to find porn (other than boomers)?
