If the built-in PDF viewer annoys you that much then you could use KOreader instead.

I've bought Aura One mainly for reading scanned paperbacks/hardcovers that make majority of my current pdf books and although those are easily legible in Aura One's portraite (12 cm width) they are also as legible on Kindle DX portraite (14 cm wide).
So, here's a side-by-side test. I'm using a page from Tsutomu Nihei's "BLAME!" manga. This particular page shows off a lot of different kinds of detail: lettering, line art and zip-a-tone shading. The examples are this file processed with ImageMagick to match the native PDF viewer resolutions of each device and then photographed with my less-than-magnificent Pixel 3a.

The first photograph is the DX pdf on both Kindle DX and Kobo Forma.

Aura One is 1404x1872 if you want to perform a similar comparison with that device.
