Never heard about BORE scheduler. It is an additional patch to the kernel ? How stable is this ?
You could go into their wiki. It's linked from the page, and skim/skip over that installation stuff, until the chapters where they explain what they did to the kernel(s), how they compile and link optimized, schedulers, and stuff. It's not ultra-thourough, but gives a good overview.
I've settled on sched_ext: BPF scheduler "bpfland_1.0.18_g5bff813c_dirty_x86_64_unknown_linux_gnu" -powersave for processes, and let mq-deadline handle internal storage, and bfq anything connected via USB.
What do you mean by "stable"?
Gaming distros trade stability and security for performance. IMHO they're only useful for FPS bragging rights. Most popular distros should already be performant enough for gaming purposes.
I don't think it is only for bragging rights, while in a vacuum the mainline kernel should be good enough for gaming, it is not really good when there are multiple tasks competing for the CPU attention (and this is especially bad for gaming because this can create a frame spike, ruining the game experience especially for multiplayer games). I think fixing this particular issue is one of the reasons Bore scheduler was created.
Speaking as a long time gamer, at least on Ubuntu, I've never seen the issue you're describing.
Try running a long video conversion job that uses up all cores while running a game, no matter how much you fiddle with scheduling priority the performance in the game might drop by 50% and frame times will spike multiple times over. Even if you try reserving some cores for the game, performance will still be much lower.
Thats a weird and rather baseless assumption for you to make. They dont trade stability nor security, their tradeoff is package compatibility between x86 versions and focusing on execution latency rather than total throughput.

As in? When I tried it, nothing crashed/segfaulted/appeared broken for the ~week I was using it, various workloads mostly programming with Rust, Python, PyTorch and Clojure.
I have no idea how stable it is but it seems it's a scheduler that weighs processes based on burstiness?
