For writing anything more than a note, I use two apps: Ulysses and Word. I like one of them and tolerate the other. I'm just going to tell you about Word today, the one I tolerate.
If I weren't a student and a teacher, I would never touch Word because Ulysses is absolutely sublime. If your document has footnotes, however, you should be using Zotero, and this means using Word on a Mac or Windows computer. So for the dissertation and any conference papers, I turn to Word. Word also gives you more control for precise, quick formatting, which I need for writing assessments.
For about the past year, Word for Mac has worked well with right-to-left scripts like Hebrew and Aramaic. For a couple decades, Word and Mac didn't play well together. I you were doing anything with Hebrew you had to use something like LibreOffice or Mellel. Many people don't realize that this era is over. The only remaining Hebrew/Aramaic hang up is the fact that the vowel points in SBL fonts do not align correctly. As I understand the situation, this is SBL's problem and not Word's. My school allows the use of Times New Roman font throughout the entire document, and I actually like the look of TNR for Hebrew, Greek, and English. It's not my preferred font, but for technical writing it's easy and everyone has it on their devices. The only situation where you will run into a problem with TNR is if you want to put diacritical marks above a Hebrew letter to mark the letter as "partially visible" or something like that. If you are working with DSS transcriptions, you will probably still have to use SBL Hebrew and Mellel at this point. Hopefully SBL will update their fonts soon.
The real draw towards using Word is that your documents are easily shareable. The chances are that whomever you want to share your work with uses Word. But there is another significant benefit: the iOS app works pretty well, especially if all you need to do is edit documents on the fly. During the past school year, I would take only my iPad to class, and when we found a typo in a quiz, I would fix it right away in the Word iOS app. Occasionally, I would print handouts from Word using Readdle's Printer Pro, and maybe once or twice I actually wrote a quiz in Word for iOS. This became problematic for the vocab sections of the quiz because for some reason with a multi-column layout combined with Greek polytonic characters, Word began acting crazy. The cursor would jump around all over the place when I would start typing.
I don't think you can create new character and paragraph styles in Word for iOS, but if you open a document that already has styles applied, you can use those styles with the same document. I think you can also save a blank document as a template with the style you want, and just start there.
One other thing the Word iOS app does really well is work with cloud storage. You can log into your Google Drive, One Drive, or Dropbox accounts and open files within the Word iOS app. Word downloads the latest version and opens it pretty quickly. While you are working in the document, everything automatically saves, and when you leave the document, Word uploads your changes to your cloud service. Everything stays in sync.
I really prefer to write in Markdown, and that's where Ulysses comes in. But good old rich text word processing is still necessary for the time being, and Word isn't bad.
