Obsidian vs Evernote
Obsidian is based on linking together plain-text Markdown files. It is a lot more sophisticated in its note-linking abilities than Evernote. You can easily build and navigate whole knowledge bases with Obsidian.
Evernote is a powerful note-taking app, supporting a wide range of ways to capture and organize various notes, todos, and ideas. Though it supports linking, that is not its strong side. With Evernote, you can capture notes in any format, from any place, and on any device, with seamless syncing between them.
