I prefer it as I don't like the following things about the kobo: ads for their stuff on the front page, and cumbersome sync (they seem to use a sqlite db to scan the loaded books on each sync, which for my ebooks takes a long while.) By comparison, pocketbook is what I want in a device: a file manager like interface to access my library, no fuss sync (via rsync and usb, primarily - I use their cloud to store books to read across devices), a good ecosystem of third party installs, and a front page that just features my books instead of whatever they want me to buy.
