This does not mirror my experience. I have a machine with amdgpu drivers installed. I specifically installed ubuntu instead of arch or something more exotic because i knew there would be issues. And i was right. I can use the OpenCL now but I can't use x11 because the driver uses old ABIs. My experience with Nvidias binary blobs even on systems like freebsd has been stellar in comparison.

You should try Arch. I'm using AMDGPU with X11 on Arch since late 2015 (when full support for my card entered the mainline kernel) and I had exactly zero issues. Just installed the driver packages, rebooted and everything worked (xrandr, power mgmt, OpenGL, games, etc.).
Maybe your issue is trying to use the proprietary blobs (aka AMDGPU-PRO). I never used these (and I don't know why I should).
Why are you using the closed source driver?
I'm using amdgpu on FreeBSD (-CURRENT, drm-next-kmod), with Vulkan (RADV) + Wayland, it's awesome :)
Yeah, OpenCL is a problem, clover crashes, the new AMD OpenCL driver is not ported yet (I guess it depends on kernel 4.15? we have amdgpu from 4.12 for now)...
I wish people started using Vulkan for compute instead of OpenCL!!

Wait Vulkan is for compute like opencl is?
It does both compute and graphics.

Compute is something of a problem for AMD GPUs right now. The open source driver is wonderfully stable and performant for gaming but to use it for OpenCL you really want to use the proprietary driver instead which is also pretty performant but sometimes has weird behaviors.
