The best way I have found is to create a SMB network folder on your local wifi network (you can do this in Windows and Mac, its usually the default folder share method in the OS, or you can use a NAS) and then use TotalCommander to move the entire Android filesystem (or just the DCIM folder) to that network folder in one go. It took me about an hour to transfer ~128 GB over wifi.

Do not use Android File Transfer (its a horrible app that transfers in a weird slow serial mode over a wired connection). Do not use Pairdrop/snapdrop/etc. Those Airdrop clones do not handle big folders of files well.

If you have Windows available, ignore my advice and do that. It probably isn't as difficult as Mac.
