- They have their own Index, and don't just rebrand Google or Bing search (but they also consider other indexes for some results)
- They have Stephen Wolfram on their board and are integrating Wolfram Alpha in their search results
- They have no incentives to show you enshittyfied content (ads, sponsored content, affiliate links, SEO bullcrap) as they have a classical subcription model instead of data based one.
- They filter out sites with a lot of trackers and ads (20+)
- They boost pages from the "small web" 

 Their search customization options are a plus as well
