On Monterrey 12.6.1 (M1 Studio Max) and iOS 17.0.3 (iPhone 14 Pro) the AirDrop speed difference is substantial if the devices are not connected to a router at the time of the AirDrop. I get about 28 MB/sec when my wifi network is connected (5G, fast) and 90 MB/sec when I disconnect both phone and Mac from the network.
The easy way to batch transfer files is not via the camera apps themselves but via the Files app. In the Files app one can select as many items as one wishes (from one folder) and send them all at once.
Do not try to line up two or more AirDrop batches together. It seems to slow the whole process down and even make it fail.
The three times faster AirDrop speeds make transferring huge ProRes video files a whole lot faster than even Lightning (30 MB/sec). Lightning via iMazing is perhaps a little bit simpler (just plug in the phone and choose the folder and transfer files to the folder of one's choice, no need to turn on all WiFi and Bluetooth and disconnect from the existing wifi networks).
More testing – AirDrop is unreliable and fails unpredictably. Failure usually require rebooting the iPhone to start working again. AirDrop seems to work more reliably with single large files or multiple small files. Multiple large files seem to be an issue. If I end up with some really huge video files I might send them individually via AirDrop to get a head start on transfer but the bulk of transfer will be done via Lightning and iMazing.
For really big sets, I might have to leaver the phone to transfer overnight (I have the 1TB version). 500 GB over 30MB/sec Lightning connection is 2h37m of transfer.
