If you need a computer that's reliable for office work, use Debian, if you want a more console-like experience and less likely it'll break your computer, use bazzite, if you want to be able to use new hardware, the moment it's released to the market have the best compatibility with all games and software and the widest range of supported hardware and software use cachyOS.

Debian is stable because it updates so slowly. It makes sure everything works under pain of death. So having compatibility issues, new hardware being supported, having to do weird little things for a less than popular application is pretty normal. But if it works, it's literally the most stable thing you can possibly put on a computer.

Bazzite it's kind of your middle ground. It's up to date in 95% of all cases while support. Basically everything but it is immutable which makes it hard to tinker with or change things should you need to. Which is both a benefit and a downside. Does mean you're less likely to break your computer while you're learning on the flip side.

CachyOS is based on Arch the most up-to-date core that you can have for any computer. It's what steamos is based on in many other bleeding edge options. It has a focus on hardware support, gaming support, software support doing so as up-to-date as physically possible. If you need something to be supported, it's more likely to be supported here than anywhere else. While the old joke Arch likes to randomly break itself isn't untrue. It's also about 15 years out of date in how true it is. Modern Arch rarely ever breaks and when it does so will every other option barring debian almost exclusively.

Realistically speaking, when it comes to actually installing and using any of these options day-to-day, they're completely identical. Typically, if you have the ability to rub two brain cells together, read and have even a 5th grade level of critical thinking skills. If you're planning on gaming as your main use of your computer not work, not art, just gaming, just use cachyOS.

There is one last thing to be aware of when choosing any option. If it's based on Arch, it's going to have the best documentation in the most user-friendly possible way. Arch has the single. Best, wiki there is. Which for a new user can be a godsend if you actually know how to read.
