I'm amazed by the feature set the app offers. The speed is unmatched due to working with local .md files, and the customisability with plugins and JavaScript is phenomenal. I'll definitely get back to this one soon!
Obsidian is by far the most valuable product I interact with on a day-to-day. I've been using it since the beginning and the evolution of the community and product is so beautiful. Obsidian is quite literately my second brain until I die.
