MuPDF vs calibre opinions
bluMystMuPDF runs blazing fast. It was made for power users and is probably not going to be intuitive to people who don't use vim. You can view a list of keybinds with F1.
Sadly it doesn't have a table of contents on the side like calibre does, and this is a dealbreaker for me..
