I did a few experiments, as follows:

(1) Start from DOCX file, public domain texts of a few hundreds pages. Convert to filtered HTML using MS Office.

(2) Use Calibre to convert the HTML to EPUB and MOBI and AZW3.

(3) Use KindleGen with option -c2 to convert EPUB to dual-MOBI and them KindleUnpack to extract the MOBI and AZW3 from this dual-MOBI.

Finding: the MOBI and AZW3 files generated via (3) are extremely small as compared to those generated via Calibre. Something along these lines:

- calibre MOBI = EPUB * 1.40
- calibre AZW3 = EPUB * 1.70
- kindlegen MOBI = EPUB * 1.10
- kindlegen AZW3 = EPUB * 1.15

What is your preferred working pathway, and why specifically? When do you use KindleGen for conversion and when Calibre? Why?
