What is Reddit's opinion of Byword?

From 3.5 billion Reddit comments

Ulysses. It's a minimalist but fully-featured Markdown editor. Its library model and iCloud integration between macOS and iOS make it perfect for notes and journal-like use cases, while its editor is built to be super immersive and the ideal workspace for writing extensively.

Special shoutout to ByWord for being an even more minimalist alternative that I'd still be using if I wrote any less than I do now.

What about it is so attractive compared to say, writeroom or byword that they mention in the article?

I had never heard of Wordstar, despite growing up with DOS heh.
