FWIW, I personally never use Apple Books.app as it is non-standard (does not meet the epub3 spec) and has bugs. On Apple Desktops I use many different e-readers including the latest Thorium Reader, the Kobo Desktop reader, and ADE 4.x. Calibre's reader is quite good also.
On iOS devices, I strongly recommend the Bluefire Reader as the most compliant e-reader available with the Kobo Reader next.
Hope something here helps.
