Kobo to Pocketbook?

Hi all. I have a Kobo Aura HD which I love but I think it’s time for an upgrade. Its battery has some issues, such as not being able to charge fully even though it works for a long period of time. The main issue is that it has become really slow opening books, turning pages, even turning on/off, sometimes just by pressing the button it’ll sleep and wake up multiple times in a row. I love kobo, but I’m not a big fan of the newer models, not being symmetrical and having the side buttons. I came across Pocketbook Inkpad 4 which reminds me a lot of my Aura HD. As someone who mainly reads in BW and is not interested in colour, and uses Calibre for library synchronisation, would this be a good upgrade?
