The biggest problem I've noticed is they don't seem able to filter out those shitty auto-generated spam sites for comparisons or top 10 lists
That boggles my mind as well. Google already knows which media are actually relevant as a source. For example, if I want good reviews for electronics products, I'd go for Heise and Golem, for everything else Stiftung Warentest. Google could easily compile a list of reputable media for each country and prioritize these, but they don't - I suspect because they enjoy all that sweet sweet ad money coming in from blogspam sites and less-reputable media.

Google is already showing big brands in most cases: https://detailed.com/google-control/
Yahoo Directories was this exact idea, and it worked well, until Google's PageRank blew it away.
You still gotta do actual information analytics on the data.
