I have a lot of devices as well - syncthing can handle em all. 3x phones for photo upload, music sync, TWRP zips etc. 2x personal laptops 2x work devices + a personal VM 2x close friend party shares for easy linux iso sharing overnight And most recently, added one volunteer device for instant/eventually consistent overnight poor-man's offsite data backup. I can mix n match folders for this on the fly and feel no loss of functionality with how little I do arbitrary internet file sharing.
