Ranked in these QuestionsQuestion Ranking
Pro Libre/open source
Pro Cross platform
Emacs runs on all platforms, Windows, Linux, OSX, even Android and IOS
Pro Can be as simple or as complex as you want
Org mode started out as a simple outlining/note taking app. Then each outline heading can optionally be a TODO list item. And if you desire, you can add SCHEDULE and DEADLINE dates. (Schedule being the date you'd like to start the item.) You can customize the TODO states to add things like DELEGATED, WAITING, BLOCKED, etc.
Pro Exports data to PDF, LaTeX, HMTL and other
You can even build presentation or blog from your data
Pro Supports tables with formules (quite powerful!)
Pro Plain text data storage
Pro Inline image displaying
Pro Free but copyrighted
Pro Fast interaction
Once muscle-memory sets in, can be much faster to use than a point & click program.
Pro Uses Emacs
Pro All apps
Pro Open source
Logseq is opensource.
Logseq is a privacy-first tool for thought.
Pro Networked notes
Similar to Roam's technique of letting the notes flow with links to each other.
Pro Daily journal is capture on Steriods
The daily journal feature allows you to quickly capture disparate topics under today's date and by way of tags make things organized and findable from any topic page.
Pro Local-first software
Every topic is its own flat file. Nothing is better than keeping your data in the file system with an option of git source control or online backup.
Pro Structured data over willy-nilly formatting
Lots of apps are too graphically flexible in how they allow content to be entered, placed, and formatted. They act like Word when what you want when authoring content is Markdown. Content and semantic structure, not graphical frills.
Pro Org syntax
Logseq support Emacs Org syntax out of the box.
Con Complicated to get started
Con Obtuse documentation
The documentation assumes a level of understanding of basic Emacs usage that not all users may have.
Con Difficult to use as a database
For example, if you need to quickly populate client details on quotes, unfortunately its easier to find, copy & paste.
Con Not suitable for normal users
Not even a majority of software developers can be bothered to use Emacs (or VI, for that matter).
Con PDF export can be difficult
Latex assumes you're a (compliant) student, have to do a lot of research to get what you want out of it.
Con Uses Emacs (for those who prefer vi, menus, etc.)
Con Keyboard-driven editing/navigating is descent but average
It is only because I was a long-time Checkvist user that I say this. Checkvist has keyboard-driven controls which are in a league of their own.
Con Still in Alpha
Logseq is still in Alpha and is under heavy development.
