What kind of issues do you have with Preview viewing PDF's? I'll admit I do need to use Acrobat to fill out most forms that Preview seems to choke on.
I have this issue on a 2012 and 2015 MBP as well as on a MP 5.1. With the built in screens, Eizos and a NEC SV. The only thing thats common across all builds is the OS.
If you think you dont have this issue, compare the rendering of Preview.app at 100% with that of Acrobat.
> At 100% zoom level, the type is not rendered with crisp edges. It looks as if someone had applied a mild gaussian blur. Only once you zoom in, the outlines are sharp as they should be.
a number of times.
Running on a 12" (Retina) Macbook w/ macOS 10.13.4 and Preview 10.0 (944.5).

It also happens within the PDF viewer in Safari - text and icons look a lot crisper when zoomed in.
