I actually just like some of the plugins in Obsidian like the LaTeX suite for its snippets. I found it cumbersome to manage the Markdown files and I get reminded of that cumbersome feeling when looking at the file explorer. There's also that property relations are not a first-class citizen in Obsidian from the start. If I use Dataview then it's no longer just Markdown (and is specific to Obsidian), and relations are just better handled in TiddlyWiki (even with the recently released Properties pane in Obsidian).
