This assumes one is able to/wants to hack their device to add KOreader, or other software. The Kobo built firmware hasn't really improved much IMO since the Aura HD came out although there have been plenty of versions. It goes forwards a step sometimes and backwards a step at other times.
It is not really accurate to describe the alternative readers as a hack of the Kobo software. The Kobo software is fully functional, in fact the alternative readers can be launched in the same manner as a book is selected with the kobo software. They can all coexist side by side.
