When comparing MultiMarkdown Composer vs Byword 2, the Slant community recommends Byword 2 for most people. In the question“What are the best Markdown editors for OS X?” Byword 2 is ranked 2nd while MultiMarkdown Composer is ranked 12th. The most important reason people chose Byword 2 is:
Byword de-emphasizes the syntax itself while emphasizing its effects. It appropriately adds style, like italic and bold, to text that's designated by markdown and dims the syntax so it does not get in the way of comprehension. Additionally, there are commonly used hotkeys (⌘b, ⌘i, etc) that can be used to apply style without having to know the syntax or having to type it out each time.

Cons
Con Table of contents gets out of sync sometimes
If you keep the auto-generated table of contents open while you work it gets out of sync, meaning items in the table of contents (at the end) disappear until you restart the program.
Con The way the preview shows images is inconsistent
The preview is a bit inconsistent with images. Sometimes it shows the image correctly, sometimes it shows a blue question mark.
Con No support for code blocks
I need my markdown editor to support code blocks like
def foo(bar, baz):
qux()
This one does not.
Con Publishing requires additional in-app purchase
The feature to publish Markdown files to web services costs an additional $5 of in-app purchase.
Con Expensive
Con Limited customizability
One of the things that makes Byword so easy to use is the fact that it needs very little setup and option-tweaking. However, that severely limits the ability to customize the editor itself. For example, there are only two themes available, a light one and a dark one.
