Using a word processor (MS Word, Apple Pages, LibreOffice Writer) is nearly as bad as using LaTeX (in some cases, worse).

Using a plain-text format like Markdown, ReStructuredText or AsciiDoc is likely better in almost all cases.

Plain text formats like Markdown work great if you don't care at all about the specifics of the final formatting. Tools like LaTeX are for when you care deeply that the resulting document follows a certain format, but don't want to think about that formatting while writing.
