I have been done some testing on location tracking between iOS App for Home Assistant and the iCloud Integration
The verdict of 2020-02-08 is quite clear, the iCloud integration is way more precise than the iOS App.
Anette:
The picture icon is the device_tracker.awn_icloud and the AWN icon is the device_tracker.awn_ios.
The real location is where the device_tracker.awn_icloud points to.
Normann
The picture icon is the device_tracker.bnp_icloud and the AWN icon is the device_tracker.bnp_ios.
Again, the real location is where the device_tracker.bnp_icloud points to.
Christopher
The picture icon is the device_tracker.cwpn_icloud and the AWN icon is the device_tracker.cpwn_ios.
Again, the real location is where the device_tracker.cwpn_icloud points to; although the device_tracker.cpwn_ios is acceptable.
