Hi to all, I broke my old Kobo Glo and I'm looking to a new ereader. After being not sure between the 11th gen Paperwhite and the Libra 2, but the freedom of the kobo's world is too much on my chord

Said that, I hope not to break any rules because I read something about this argument in this thread only two times in 29 pages:
Is it possibile to sideload mp3 or anyother type of audiobook file and enjoy it?
Because I think, my humble opinion, that there are so many ereader that have very similar performace that the choice is more appeal than difference in real world usage.
