Obsidian for sure. You can export the pdf with the same styling you see on screen.

You can also use it to make your book a knowledge base.

Check out their docs for an example of what can be achieved.

I like Obsidian and use it everyday, but I wouldn't consider it the best option for writing something as large and complicated as a book.

Books are huge undertakings that require a lot of data management and formatting specifications. I don't think Obsidian is particularly well suited to this task, based on what I've experienced.

First, Obsidian's .pdf export/formatting features are nearly non-existent. I struggle to print 4 page documents that are enjoyable to read. Formatting their book as a .pdf will get very tedious very quickly if anything other than the most basic, raw, formatting is needed.

While I love typing in Markdown for notes, Obsidian has almost no native features to help you format long form work. Perhaps there are plugins that grant these features, but I'm not aware of them.
