A BOOX device is basically an Android tablet with an eye-friendly e-ink screen. The nice part is that you can install whatever book store you want on it, you can get the Kindle, the Kobo, Libby for library books, Moon+ Reader, or any other reading app you want. You're not locked into one ecosystem.

The other thing is that BOOX devices are for writing and productivity, not just reading. They have stylus support and fantastic note-taking apps built in. So you can mark up a PDF, take meeting notes, or split the screen to have a book open on one side and your notes on the other.

So, while a typical ebook vendor gives you a closed device to consume their content, BOOX gives you an open, flexible tool that you can use anyway you like.
