No te fíes de las imágenes ya vengan de uno u otro servicio (bing, mapbox o
Google) si el proveedor es DigitalGlobe y la imagen es la misma (podría
darse el caso) el desplazamiento y el error será igual. Unas están mejor
ortorectificadas que otras.

Adjunto archivos XML que debes de cargar como si fueran raster para ver las
tiles con imágenes de alta resolución desde el servicio de mapbox y el de
mapquest (este suele tener las mismas imágenes de bing). Recuerda que la
proyección será EPSG:3857 (Pseudo Mercator).

Un saludo
