The new AI summary 'widget' at the top of the results area is the compelling differentiator from other search engine options IMO. Often people are searching for a simple answer to a question, not a list of links that we have to evaluate and then go off and read to get that answer. By summarizing and answering the question at the top of the search results, while also creating a dynamic subset of reference links used to generate that summary, it's a fairly comprehensive approach to satisfying the balance between 'just answer my question' AND 'but let me quickly and easily dig into the details (curated best list of sources) behind it if I want to'.
