How do you feel your data for Kagi Maps compares to Google Maps? It's the kind of thing that's harder to test than switching web searches over to Kagi. I need to already know that the business and transit data is reliable which is why I still go to Google Maps.
Local queries are the I've things I use Google for still -- but Kagi makes it easy, you just start your query with !g and it redirects you. So it's pretty safe to switch the default.
