Pros
Pro Cloud syncing
With an account for syncing on their servers, you can run the brain on multiple computers.
Pro Good support
Worthwhile support is offered, especially for those that pay for a subscription.
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 Expensive
There is either a $15 a month subscription fee or a license that ranges from $219 to $299. There is a 30 day free trial for those who would like to test it before subscribing or purchasing, but overall to use this app it can be pricey.
Con High learning curve
There is a little bit of a learning curve with all software, and this is no exception.
Con Obtrusive, like someone WITH CAPS LOCK ON
Too loud, too much going on, and definitely an in-your-face sort of feeling.
