I was wondering also. If it can help, there is an overview on Kitty's website : https://sw.kovidgoyal.net/kitty/

Compared to Kitty, Konsole has image preview, click on files and links, tabs and tiles. Konsole does not have a way of changing the layout of tiles, equivalents to Kitty shell and remote control, pager, and the ssh integration (e.g. ls in an ssh session and Konsole will not open the file).

I dont get it. What exactly does kitty give use here?
