FreeNAS rsync vs syncthing

Hi Tom, just finished watching one of your FreeNAS videos where you used Syncthing to replicate data. Do you prefer Syncthing vs Rsync? If so why?

To say I am grateful for your work (youtube videos) is a vast understatement! Keep up the great work!

Syncthing is real time so each time I edit a file it replicates it over to all the other sync thing locations both local and remote.
