IMHO Kindle is not a good e-reader. It’s not yours, and the books on it aren’t yours. Amazon can wipe it without your consent
My extended family and me have been using Pocketbook readers, all the models we bought over the years are good, price is ok, and the oldest is at least 7 years old now and still works great. They support their own free cloud service, sending books by email, dropbox, calibre, and of course you can simply plug them in and copy ebooks. Some models support audio books.
Larger models with color e-ink display exist, I heard- good things from people who read comix, but I find them too expensive, and too big.
