I used to use syncthing few years back. I don’t remember much about it and I can’t even remember why I ditched it. It probably wasn’t any disasterous situation - I’d remember that, but there still had to be reason I did it.
What I remember I specifically used one way sync of photos. I don’t do picture editing at all and I tend to sort pictures on drive differently than one huge pile on phone, so this was what allowed me to do my shit easily.
Different people, different tastes.
