I have the same laptop and I want to keep it. I would like to say that
practically everything is working except:

* Suspend and hibernation,
* 4k60 via USB-C's display port. I use HP's G5 docking station and this is 
working in Windows.

Both issues can be replicated on kernels 5.8.5 and 5.9.0rc3.

The 4k30 works just fine but 4k60 freezes both screens until it's
switched back to 30 hz after 20 seconds.

I tried to use fwts to test the suspend so I am attaching results.txt
here. Maybe it will help to identify the issue.

** Attachment added: "output of sudo fwts s3"
