The big win is using standard markdown. If they disappear, you still have your content. The other big win is it's truly cross platform. I initially used syncthing to keep different systems in sync but switched to their sync service. Syncthing works fine but I found adding a new system and integrating was cumbersome if you haven't done it recently. With Obsidian's sync service setting up a new system was trivial. Shortcoming - printing. Need to generate a pdf and use it's print feature. Another shortcoming is merging a hierarchy of folders and notes into a composite document.
