Aura One and pdf experience

Hello,

I am thinking about buying either Aura One or Kindle Voyage. For me a big issue is the pdf experience. I saw many videos/reviews saying that Aura One is simply ridiculously bad with pdfs which is a shame given such a nice screen.

Is it possible to install some other software to handle pdfs in Aura? Do I have to root my device?

Assuming it is possible, will the pdf experience will be comparable with Voyage/PWs/Oasis with their fast reflows and such?

Many Thanks!
