It works perfectly fine if you use the closed source drivers..it just needs a few extra steps.

There's always this deluge of posts of the absolute horror of nVidia in Linux.

Yes, nVidia is an evil capitalistic company. No they don't care much about Linux. Except when it suits them. Right now it's in the data center.
But then, AMD doesn't care that much either. Why would they, there aren't really any Linux users. They're both soulless corporation that would sell your children's kidney's without a second thought if they could make a dollar from it.

Now in practice, whatever you use, stuff mostly works 99.5 % of the time. There's no difference between nVidia and AMD (or intel), they all work fine.

Don't get drawn in stupid corporate dick sucking contests, it's completely pointless. Use what you want, or what you have, it doesn't matter.

I have an rtx card and the only issues I've experience is a resume from suspend/hibernate bug where it locks up. I just disable sleep/hibernate, let my monitor turn off still, and shut down my PC whenever I'm done.

EDIT: I also have had the best luck with arch but I'm picky about pre installed software.

I used an nvidia gaming laptop on different distros for more than 5 years without any issues. The nvidia driver works great. The only thing lagging is the noveau open source driver like mesa for amd.

Not so, if you are OK using x11 you will probably have zero issues. Wayland support, however, is shit. I had a 1660 super when I switched and it was good. Just when I had two monitors with different refresh rates it get weird, x11 does not support it at all (there is some workarounds but they are workarounds). Wayland fix the issue but nvidia support for Wayland was veeery bad at the end of last year, when I switched to AMD.

The thing about being open source is just that the community could help move things faster and would not need to wait the good will of nvidia for everithing, but nvidia is still moving slow towards open source, it does not means that they aren't doing things and fixing bugs, just they are a bit slow and stubborn

I can see how you would get that impression, but it is false. NVIDIA drivers are mostly fine today. They used to be abysmal, and still under the hood don’t work like everyone wants them to. The do, however, work. And for the most part they work well. Wayland can be a bit buggy, but I’ve been using kde Wayland for over a year now on an older nvidia system and I have experienced one bug that was a minor inconvenience.

It works most of the time, but since NVIDIA is the only one fixing your drivers, chances are your bugs won't be fixed.

Not true at all anymore. Distros like NobaraOS set things up by default (and increases gaming performance by ~4% over fedora according to Linux Experiment) so you don't really have to worry

It's just not as convenient as AMD for power users

I’ve found that Linux tends to be a much better experience with an AMD GPU. The nvidia driver is mostly fine but would regularly cause my desktop to crash.

Depends on your expectations, it won't be as streamlined as amd/Intel but if you are not too picky it should be enough to have a usable machine.
