It is crap enough for me (RX 5700 XT user) to keep a backup of the few previous successful drivers so that when one inevitably breaks things i can roll back to a previous driver.
Some issues i had with a variety of AMD drivers on my current PC from the top of my head: turning on the monitor before the PC would cause the GPU to not realize there is a monitor attached, letting the monitor to go to power save mode would also cause the GPU to think the monitor was lost, settings for display scaling would be lost after every full reboot (full=real reboot, not the fast hibernate based one Win10 do most of the time, you get a full reboot after updates, some installs, etc), random full system hangs when trying to play GPU accelerated video (which is pretty much most videos on web as well as some applications like Microsoft's new XBox Games app), random reboots too, etc.
So i tend to be careful with updating the drivers. Last issue i had wasn't as bad the random hangs/reboots (which fortunately hasn't happened recently) but i simply couldn't launch the crimson UI at all. I had to do a full reset and reinstall of the drivers for it to appear again.
In comparison updating to the latest Nvidia driver when i had an Nvidia GPU (which was since early 2000s to ~2 years ago) was basically a non-issue: i wouldn't even think twice about it as i never had any issue.
And FWIW that was the same on Linux too: i never had issues with Nvidia's drivers there either and performance was more or less the same (at least for OpenGL stuff). But note that i avoid stuff like Wayland, hybrid GPUs, etc like the plague.

I have a similar issue with a Dell display attached to an AMD card. After suspending the PC, the monitor does not detect the PC at the other end of the DP cable, except for Amazon Basic cables which work for some reason. Digital standards are weird.
This back and forth in this thread about nuisances like that is one of the reasons I am definitely sticking up to Intel integrated GPU when running Linux. It's 2020 and stuff like that should be much smoother :-(.
Note that in my comment above i was referring to the Windows AMD driver. I haven't used Linux much with this machine (though when i did it had a 50/50 chance to completely hang the system, but i think this was an issue with the kernel and the then-new Zen APUs that was quickly fixed).
I have Lexa PRO in my workstation (Fedora) - Suspend/Resume works so far.
I have an issue though where switching off the monitor for a few days might make the AMD card disabling the outputs and not recognizing the monitor afterwards (I think it is related to the order in which I try to "wake" the monitor) - which I cannot recover from without rebooting the machine.
But this is with a machine never going into suspend or any sleep state - and I can't say if this would be the same with the NVIDIA card. I do not use the NVIDIA card for video output because the proprietary driver would regularly stop showing my desktop - or suddenly any output at all after reboot.
The integrated Intel GPU on my laptop is mostly without issues whatsoever.
On laptops I would still recommend Intel GPUs anyway for power consumption reasons - although AMD APUs are quite interesting and I don't have recent knowledge about how well they compare. The CPU and its ability to lower power consumption under sleep is also relevant there, and this was way better under Intel so far. Unless you need the increase in performance an AMD GPU/APU would offer...
