Don't know much about SecureBlue but Kicksecure isn't comparable to Qubes at all. It's a hardened distro, not a way to isolate workloads through virtualisation. Depending on what you're trying to achieve they can both fit but they are fundamentally very different in their approach to security.

Secureblue is essentially as close to GrapheneOS as Desktop Linux can get. Neither my response nor the original question required qubes comparisons. It was merely mentioned.

While secureblue is a full desktop distro (not just a kernel) that integrates key grapheneos hardening tools like their hardened malloc and forks of their hardened chromium and works with flatpak as a base for hardened application deployment.
You are literally saying that hardening the kernel is the same as having the desktop environment hardened and a basis for app isolation. And to add a cherry on top of that both secureblue and kicksecure use almost all the same hardening additions to the linux kernel as grsecurity.
You do not understand what you are talking about because if you did you'd be embarrassed for how braindead your response is.
You have already proven you don't understand the difference between kernel and userland hardening, why should i bother working for you, google it yourself.
