I'm not sure what your experience was or how long ago, but syncthing is one of very few programs I've ever had 'just work,' like absolute magic. sudo pacman -S syncthing, syncthing was all it took to stand it up, followed by extremely minimal in-app setup that was no more complex than working a modern music player. It keeps everything synced across my PCs and my mobile without any intervention on my part.
