Wich do you find better, SyncTrayzor or Syncthing GTK and why did you choose the one or the other?
“SyncTrayzor”, not “Sync Trayzo” 
I just tried both and, at least for the time being, will stick to SyncTrayzor because it looks more “native” to windows, and seem to implement it’s own mechanism to detect changes to the filesystem (called “folder watcher”), instead of spawning a third process for syncthing-inotify. But I’m interested in what others are using as well.
Now i am only on Syncthing GTK bekause i changed from Windows to Linux
