Can I assume orthoimagery is the best for tracing buildings? (self.openstreetmap)

I'm trying to correct local buildings on OSM. I've noticed that some of the buildings were traced before according to one set of satellite images, but are off according to others. One of the options for a background while editing that I've got is called orthoimagery. Can I assume that that is the best set of satellite images for tracing buildings from?

In some places there are government basemaps available as well. These can be extremely accurate, up to centimeter precision. Of course they can be outdated or have mistakes too, and not all are as precise. So it's hard to answer the question without knowing the location. Always vest to consult with local mappers about things like this.
