How would you define a good result for that query? It seems like the only thing you could expect from that query is a page of advertising, since the "best X" without any criteria is a concept that doesn't exist in reality.
Somewhat true. A perfect awnser for such a query would be a page like tomshardware where the best smartphones for multiple categories would have been nominated.
A normal Google search actually does return that, after some scrolling. This however is ofc heavily based on my browsing history.
