When comparing Byword 2 vs IntelliJ IDEA, 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 IntelliJ IDEA is ranked 23rd. 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 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.
Con Is not free
But it does have a free version (Community Edition).
Con Heavy
Consumes more resources than VSCode etc. But depending on your use-case, it can still be worth it for the benefits you get with this editor.
Con Autocomplete does not work while IntelliJ is indexing
But this, in general, is not much of an issue. Usually after npm install, etc.
