I do use the GUI, but I have to agree in the ebook-covert tool being top notch. I once pulled a massive amount of books and videos from a particular publishers online platform. I can't remember the details but I wanna say the tool I used left me with html files with images stored in various folders or something. Ebook-convert handled thousands of books with very few having some formatting issues or outright failures. Most of the issues were the tables being way oversized and the text inside them not scaling correctly. I suspect I could fix this fairly easy, as I do still have all these books, but I just haven't gotten around to it. My data hoarding tendencies start to come out when scarcity is on the horizon and I will waste much time archiving something I'll never use on occasion.
