If reading anything other than PDFs is important the Boox is a better choice. Remarkable lags super far behind in ePub support, AFAIK it converts an ePub to PDF and then displays that. A large book will take a very long time to adjust the font size or other formatting because of that. General rendering support seems poor and it doesn't support any DRM scheme or library system so you're stuck stripping DRM off books and monkeying around with their app to get it onto the device. Boox of course can just run the Kindle or Libby Android apps.

Main thing people like about the Remarkable is writing feel which mainly comes down to the surface and the pen nib. You can literally use the RM pen and nibs on the Boox Air and a matte screen protector. MyDeepGuide on YouTube has recommendations on how to get a better feel on the Boox Note Air.
