I had several Amazon Kindles, and liked them very much, but then Amazon disabled transfers via USB-C so I had to look for an alternative.
I got a Pocketbook Verse Pro. The display is great, you can install extra apps on it (that I haven’t experimented with much though, I only like to read), it is IPX8 rated so you can literally dunk it in water (so I can take it to the beach, pool, etc). It also connects via Bluetooth and plays music. Downsides: it could be a bit more responsive (for large books I notice an opening lag of about 1/2s, but that is not a big deal).
(forum members advised me too, see the discussion)
