Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Possibly more secure on web server
Due to the lack of a built-in editor MDwiki may be less susceptible to spam and defacement compared to other options when served from a web server.
Pro Doesn't require a web server
MDwiki is a self-contained JavaScript app that is very fast and can run in some web browsers such as Mozilla Firefox.
Pro Focuses on writers
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.
Pro Citation support
While it supports a diverse range of 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.
Pro Almost perfect
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)...
Pro Renders math in-place through KaTex
Cons
Con External program must be used for editing
A separate program must be used to make changes to documents as MDwiki lacks a built-in editor.
Con Requires additional permissions in Google Chrome
Supposedly, you can get it to work in Google Chrome by modifying JavaScript permissions, but these same changes may decrease security.
Con Obtrusive, like someone WITH CAPS LOCK ON
Too loud, too much going on, and definitely an in-your-face sort of feeling.
Con Large, slow, can't open just a single .md file
