Why not ask your question on the new OpenStreetMap Community Forum?

What is the best source to map with? Bing vs. Esri vs. Maxar etc. Sometimes when I map a building I switch sources, adjust the offset, but it's still a little off. Sometimes Esri is straight down on a building when Bing is tilted, showing a building's walls. So, what's the better option to base your edits off of?

There is no answer that is valid for the whole world, it depends on where you are (that is one of the reasons many different sources are made available). What do other people mapping locally generally use? Are there "official" local sources available in addition to global ones like those you mentioned?

A much bigger problem is not finding the "best" image source, is not doing position calibration of the image/background.Most newbies have never heard of this and use the image as it is, without any calibration.
