Bit of a nitpick, but the comparison with the reversing of the MS Office formats is a bit tenuous, and somewhat revisionist.
Competitors and open-source applications were reverse-engineering the Office file formats long before Apple iWork was a thing, and arguably no-one really gets it right because in order to get it perfect you'd have to reproduce the Office application layouting engine exactly, bug-for-bug. Even Microsoft doesn't get it 100% from release to release.
Nvidia drivers have (slightly) more timely support for the latest cards, and more mature support for non-3D uses of the GPU, especially scientific computing. To a large extent they are the same code as the Windows drivers, and that has positives in terms of breadth and maturity of support.
For everything else, the AMD drivers are better. Because they are a separate codebase from the Windows drivers, and are part of the de-facto Linux GPU driver stack Mesa, they integrate much better into the overall Linux experience, especially around support for Wayland. Unless you have an absolutely bleeding-edge card, they "just work" more often than the Nvidia drivers. If you like doing serious tinkering on your Linux system, then the AMD drivers being fully integrated and having the source available is a major win. Also, it used to be that the Nvidia drivers did a much better job of squeezing performance out of the hardware, but today there's very little in it, and the AMD drivers might even be a little more efficient.
I've got both AMD and Nvidia GPUs currently in different machines, and I much prefer the Linux experience with AMD. I don't think I'll be buying another Nvidia GPU unless the driver situation changes significantly.
FWIW I don't stream so I can't comment on the exact situation, but I have used the video encode hardware on AMD cards via VAAPI and it was competent and much faster than x264/x265 on the CPU. I think OBS has a plugin to use VAAPI (which is the "standard" Linux video decode/encode acceleration interface that everyone but Nvidia supports).
Converted-to-Bluetooth Stadia controller.
It's actually a really nice controller. The ergonomics are great for my big meaty hands, it's got some weight to it and feels really solidly built. The heft means the vibration really has some kick to it. The battery life is really good too - it was specced for having Wi-Fi on all the time, so now it's running only a little Bluetooth LE radio, the battery is massive. Even when it runs down, the charge rate is quick - full in about half an hour, and then good to go for weeks. Again, probably because it was specced for Wi-Fi, the radio circuitry is way above average and the range is stupid - I can control a Steam Deck from two rooms away, through two solid brick walls, something none of my other controllers can do.
The sticks are accurate and don't drift, the buttons are pretty good, and the D-Pad is a bit stiff but perfectly serviceable. My one significant complaint is that the springback on the triggers is way too light, which makes it difficult to be subtle with the triggers, a little annoying for driving games.
Still, if you see one at a sensible price, they're a steal.
