Pros
Pro Keyboard driven
You don't need the mouse to use Howl. Everything can be accomplished with commands and shortcuts.
Pro Fast startup
It's extremely lightweight, making it start up pretty quickly.
Pro Easy to use
Howl is very intuitive and easy to use.
Pro Easy to extend
Plugins (bundles) can be written in Lua or MoonScript.
Pro UI Focused on editting
Non distracted icons, toolbars, pannels, extra spacing, etc.
Pro Language tooling
Has built-in functionality for completion, inline documentation and linting so IDE-like features can be added easily.
Pro Command line palette
Search for your commands in an easy way and see in the list which key-strokes are mapped to which commands
Pro Open source
Howl is an open source project and is actively developed on GitHub(howl-editor/howl). It has a MIT license.
Pro Works on OpenBSD
Pro Allows easily switching between working on multiple files
Write! has tabs at the top and a tree view on the left that allows quickly switching between different files.
Pro Interface doesn't get in the way of work
The interface is minimal, when it's windowed there are no buttons or toolbars, so it doesn't distract from work. When it's in fullscreen, there's just text, no interface at all.
Pro Endless undo/redo
Write! uses a file format that saves all versions of a document. Meaning even if the app is closed and then opened up again, Write! can restore any previous version of the document.
Pro Can double as a to-do list app
Write! has a to-do list mode that allows creating lists of items in groups (tabs) that can be ticked off when completed.
Pro Picks up where you left off next time you start the app
Write! saves the state that it's in when closed and restores that state when opened. You can pick up working on documents in the exact same place you left off - same documents open, same cursor placement, etc.
Cons
Con Lack of Lua examples
Although Howl can be extended in both Lua and MoonScript, almost all bundles are written in MoonScript. This means that it is a bit harder to find examples if you'd rather write your bundle in Lua. MoonScript can be compiled to Lua but the code won't be as clean and understandable as if it would've been written in Lua by hand.
Con You need to login to the App, and it reconnects to their server
There is no offline use.
Con Not free
There are free markdown editors for windows, this is not one of them.
Con Needs better folder document management like Ulysses
Con Needs nested folders
Con Bad MarkDown features
Not worth $20, the markdown editor sucks.
Con In beta
The app is not yet complete. A lot of the promised functionality is not yet implemented.
