Good topic, very interesting!!
I have just uploaded in the two screens about the rendering of modified Andika font (by Barty user
https://www.mobileread.com/forums/sh...ght=andika+ink) on my Clara 2E.
Same ebook, epub on the left. The epub version seems awful to me..and, it happens exactly the same with my kindle paperwhite, where andika looks softer and muche more definite, elegant while using kfx converted ebooks.
I also see some little differences among them about font size and line height. In the overall, I prefer kepub format too though Epub is standard and kobo format is a proprietary one...it's a shame!
