This. Airdrop is actually viable for transferring huge files, like RAW photos or ProRes footage. I've had video engineering professionals ask me if it's viable to implement Airdrop support in something like a camera or a recorder, not because it's pretty or doesn't need cables, but because it would save them time in a media workflow (they are busy people).
Resilio Sync's pretty fast and less fussy than AirDrop, I also don't like keeping AirDrop running chronically
Resilio Sync is also incredibly slow when the two devices are not connected to the same network. Like kb/s slow.
