Maps are still pretty good. I use street view and the reviews and opening hours a lot. Which competitor can I use for that? I think the driving directions may have got messed up by merging with Waze.
Yes, the reviews are still very good, but I think this is more due to users (as a 6-point local guide myself) and less due to google.
I am seeing bot-generated reviews more and more often, and when I look at what happened to search, I don't have a lot of faith in google to do a better job with maps. But I sure hope they do, because I'm with you - I really do rely on maps reviews.
