I'm in the same situation. I've read some workflows you can do but I really like to just pop open einkbro with my royalroad follow list as the homepage instead of having to run a browser extension to calibre rube goldberg machine every single time a new chapter is released.

I don't love boox but mine hasn't died yet and it's decently competent at my use case.

screen is not as crisp and a lot of ghosting

Can confirm. I own a Poke 5P and the ghosting is really more obvious until you've fiddled with the settings enough - and I do mean fiddle here. Might take a while.

Other than that I'm a real fan: latest update delivered dark mode (black background, white text) and like I said above: no ads, no Amazon-DRM, all formats, cloud storage (if you want to), TTS, annotations that are really comfortable to handle, bluetooth.

Boox suck. Stay away. Horrible android os, low speed, battery and hardware quality issues, and dodgy Chinese practices all around.

I'm very happy with my Boox Palma. The Kindle app works fine on it so there's no fiddling with side loading Kindle books into a non-Kindle device.
