I'd rather just have/use Intel GPU over them as well, I am not a laptop gamer to need anything NVIDIA offers in exchange for the pain in maintenance using out of tree modules to me.
Depending on which distro you use NVIDIA grapics can be quite painless. Using Pop!_OS, I just had to download the correct iso from their downloads page.
I believe most other distros have NVIDIA's drivers in their non FL/OSS repos as well.
Optimus graphics will even work with the most current drivers.
I can switch to built in Intel video for better battery but it requires a reboot. I see this as a stopgap. My home machine has an amd video.
I only need the NVIDIA graphics every so often on my laptop though, so it's fine for me.
On desktop I've had no issues.
In my experience they're largely OK. There are some rough edges - you'll struggle to get Steam and CUDA working at the same time, for example - but no showstopping problems.
I certainly don't have a debilitating kernel panic every week :)
It's only MBP NVIDIA GPU in Linux (older model) that I have extensive experience on so far, and it's been terrible with nouveau.
