some of these criticisms are probably fair. I only speak english so can't comment on non-english results, but it wouldn't suprise me if the Kagi creators were primarily or only english speaking and step one is optimizing for english.

I'll also say that Google maps, while it has made some missteps in my eyes is the one good feature of Google (well, google translate is pretty good too.) and while I haven't kept up, last I heard, Google had over 1000 staff on the maps division, so, yes, I expect any mapping service is going to be worse than Google.
