AZW3 vs KF8
I just updated to Calibre 0.8.65. I have a Kindle Touch and usually output AZW3 format for it.
My question: What's the difference between AZW3 output which I have been using and MOBI output using the "new" setting which I understand produces KF8 format. I thought AZW3 output was KF8 but there is quite a size difference between the two.
Is there any advantage in using one over the other?
