Tl;dr: dislike my kindle, love my kobo libra colour. What's your favorite ebook reader?
As a 30+ year long reader, I have read many, many physical books (I still buy them 👀), but in the past 5 or so years, I've gone ~50% digital, and I have tried various ebook readers.
I've had a Kindle for a few years and I like a lot of the exclusive authors/books....lots of good indie smut hehe. That's about it tbh 😂 If you sideload your non-amazon books (I have over 2k! 🫣) it's a nightmare to deal with. You have to change the format, can't organize your books on shelves or collections (not even using Calibre!!), the covers get messed up/go missing, and you couldn't update good reads (don't use it anymore so a moot point). Not to mention the fact that they can remove "your" books at anytime! I had a whole series I spent a lot of money on just dissappear with no recompense, no explanation... Just poof!
After that fiasco, I got a Kobo ebook reader last November and I love it 😍 it fixed everything I didn't like about my kindle, and then some. I can freely organize my sideloaded books into series and collections, I can get all the same functionality as native Kobo books, and Calibre is actually useful for beyond just uploading books! Oh, and NO ADS!! There's also detailed reading stats (per book and overall), seamless Overdrive integration (for library books), and (on the libra colour) physical buttons! And they haven't taken any of the books I've bought from them, even though a series I bought was removed from their listings 👏🏾
I still have my kindle (can't get books I bought off it because they use proprietary formats and wizardry that prevents you from doing so 😞), but I exclusively use my libra colour and do not regret switching over
gets off soapbox 📦
