I just switched from AMD to NVidia because of driver issue. I run Arch Linux, and my experience is that installing NVidia drivers is miles ahead of AMD.
I run Arch and amdgpu was installed as a kernel driver out of the box. If you have an RX GPU, or any other one supported by the new drivers, you're going to have a great time.
I have experience with NVIDIA and AMD GPUs on Linux-systems and my experience with AMD was vastly superior. The difference was so significant that I rule out buying a NVIDIA card.
