Boostnote vs Zettlr

Supports Windows, macOS and Linux.

Boostnote is great for developers looking to take programming notes with code snippets and such.

Boostnote has the ability to store code snippets and comes with syntax highlighting out of the box, supporting many languages.

Boostnote doesn't require an internet connection to work. You can write notes offline and sync later.

Boostnote comes with many themes out of the box, most of which are popular themes and color schemes for code editors: e.g. 3024, base16, solarized, tomorrow.

Boostnote supports vim/emacs key bindings. If you're a developer familiar with either of them, navigation should be easy to pick up.

While many Markdown editors don't offer specific support for a certain type of workflow, or offer features for scientific workflows only, Zettlr offers features that help the writing process of journalists or researchers in the arts and humanities. It's a lot more text-focused than most editors.

while it supports many syntax (chart, easy image insert, etc.) found in other editors, the great citation support made it possible to write real articles. Citation from Zotero and Mendeley can be inserted easily which is a huge plus

After testing more than 30 alternatives, paid and free, I can definitely say that this is the best option, still not perfect, there are some bugs like creating / editing tables and resizing images, but the PROS destroy the CONS, easy quotes, WYSIWYM , attachments tab (supports attaching and opening links to any file), table of contents, TAGs, easy hyperlink between files (same as citations), export to many formats (like Word, HTML5, PDF)...
