Pros: - markdown with a lot of extensions - full-text search across all notes - browser extension to clip a page into markdown (or full html) - vim mode - can open externally in vim - syncs into folder (with syncthing can even sync across devices while not connected to the internet)
Cons: - very bad, almost unusable android app - "proprietary" hashed markdown filenames instead of standard file layout
Vim with vim-markdown-preview on Desktop, and Markor on Android. Works fine for me.
Obsidian when it's local and I need full markdown.
Google Keep to share grocery/shopping lists with my wife.
Though I use both quite infrequently.
