Camera GPS EXIF vs Manual Workflow Accuracy

What would the accuracy difference be between utilizing the EXIF vs georeferencing with a basemap vs manual GCP's?

The EXIF accuracy is likely to be better in a relative sense since it can pull from so many more locations. However, since it is relying on a somewhat cheap commercial GPS, it has the possibility of being off by up to 10 meters. The manual workflows CAN be more accurate in absolute location but tend to be off by a bit more in relative due to less information being available. There is a tradeoff.

I wonder if it would be possible to combine the two techniques?
Stitch and error minimise on the EXIF GPS info, then orthorectify to GCPs?
