There isn't anything better.
Don't tell me desktop linux. It's not fit for purpose and doesn't run the software I need it to run. I do not want to run Linux. I, frankly, do not like what Linux evolved into. The desktop linux of 15 years ago was sort of acceptable. Modern systems infected with pulseaudio, systemd, and whatever the fuck gnome and kde have turned into are not. I'd rather run Windows, and I hate Windows.
Well I run Linux since 25 years, so if you're telling me that it's not "fit for purpose" then I question your ability to see purpose.
Also I think you're cargo culting. You have problems with existence of systemd while praising an OS that doesn't even allow you to disable transition animation delays when changing virtual screens. It's not logical.
Btw, pulseaudio is old news, now it's pipewire.
Linux doesn't have a way, there are about 30.
Ultimately though, package managers (whether it's apt, dnf, Steam, some app store, etc) are the best for most people, myself included.
