If I had the choice I would have gotten a Supernote A5X because they are a more ethical company, conscious of sustainability (their pen nib does not need replacing) and they provide a road map for updates so you know what’s coming. I’m not able to get one, however, because I live in the UK and shipping and taxes end up nearly doubling the cost.
That said, from what I read, the best writing experience is with the reMarkable, though as others have said, the subscription service is a frustrating addition. They give you a year free when you buy new. This was my best option and I’ll be getting one soon.
I also looked at Boox which has color options and a back light but the writing experience isn’t as good because there is a gap in the screen where the back light is meaning its more like writing on a white board than paper.
This blog solely reviews ereaders and they go into a lot of detail: https://goodereader.com/blog/
If you mean Australia, I just checked shipping with reMarkable and it’s free.
