How accurate is ESRI world imagery basemap in ArcGIS?


I have an aerial photo which doesn't match up with ESRI world imagery basemap in ArcGIS 10.2. I didn't add the AP or georeference it. It was already in the project when I started. I'd really like to know how accurate that ESRI basemap world imagery is? I know Google imagery has issues, it shifts in Google Earth or QGISfor example. Does the ESRI world imagery basemap suffer the same sort of unreliability problem. I cannot find any information on this, but I need to know whether to trust the AP.
