Note that "Kindle for PC/Mac" doesn't support personal documents, so no point in emailing files if you want to read them on your PC.
If your files are in Mobi format, the sole advantage of converting to KF8 (AZW3) would be that you could then very easily edit a book in Calibre's editor if you wanted to change something in it. Calibre can't edit Mobi files. That is a very big advantage - the editor is easy to use and I very often edit my books if they have something I don't like (eg a wide space between the paragraphs).
