You're constantly changing the topic. At first you were talking how KFX forces styles on you, now you're defending Kobo comparisons that have nothing to do with the topic discussed.

On Kindle, we've the choice between AZW3 and KFX, and KFX in most cases works the best, even compared to EPUB, if it's running in KoReader. That's a plain fact, as far as I'm concerned. I see nothing that would disprove it. Maybe KFX is worse than other formats on other readers, I'm not judging that. But if you think that it is, I'd really like to see some proofs of that, not just pointless talk.


I think the topic if fit for a separate thread, so I'll start it when I find some time to do it. In the meantime, I've done a few quick comparisons.

All images are 1:1 screenshots from Kindle. Same book, same fonts, same font setting regarding KFX and AZW3. Major differences are in red.

Notes:
Spoiler:
Code:
Source book is an early Project Gutenberg ebook, with images of low resolution, and in high JPEG compression.
Koreader displays images at their native size.
Kindles native renderer upscales images automatically for display on pages in both formats.
KFX renderer is far superior when it comes to enlarging images to full page.
KFX Converted in Calibre (as personal document, created approximate page numbers)
AZW Converted in Calibre (disabled 'Compression of the file Contents')
EB Garamond font used in all comparissons.
No cherrypicking regarding samples and settings. Chapter 1 page on AZW3 happened to look like that. And I didn't use font fix that fixes line heights on KFX renderer.
I forgot to turn off indentation on first line in KoReader.
Book: https://www.gutenberg.org/ebooks/308 (epub3)
Cover source: https://archive.org/details/isbn_9798732072860/mode/2up (for personal test)

All books as attachments. KFX is zipped.
