I generally have three types of Linux devices I typically use. My desktop, servers locally/remotely, and "mobile" devices (more like tablets I guess).

For the first, I want the lowest latency for everything I do, together with the highest burstable speed whenever possible, for pretty much all the components.

For the servers, I basically have two types, one which does storage, they just need large disks that can be slow, and one which users actually connect to, that one needs focus on throughput, latency and performance isn't as important as "can serve all requests in a reasonable timeframe, even under load".

Finally, many of the portable devices run on batteries, so on those the focus is power-saving, even if it compromises on performance.

I'm sure others out there have more device types, like ultraweight watches, security devices, monitors, radios and much more. Each one of these have different tradeoffs, and tuning the kernel and OS for each use case makes it a lot better usually. Personally I use NixOS for everything except my desktop (CachyOS right now!), and it makes it really trivial to create profiles based on the same configuration, deployed to all devices, and today they're are tuned for exactly their purpose, as Linus intended :)
