I've been using Synology Drive to sync Obsidian between different machines and my android phone and it works great. I've never seen a need to use the official sync.

replyObsidian is a note and wiki syncing system.
You should use an obsidian syncing system if you want to sync notes and wikis. You should use a file syncing system if you want to sync files.

A very valid question is whether there are benefits to using a special note sync application rather than a standard file system sync application, and if so, what those benefits are.
