It doesn't matter what the question is antiX is the answer.
Apart from antiX in recent years making tremendous strides in being truly systemd free it is more stable than debian, since systemd keeps releasing more and more buggy complexities such as systemd-boot
antiX also has stable/testing/unstable branches, but experience from the past proves that even sid/unstable is a very usable daily work system. Sid is close to arch but +5 architectures x2 32/64
I'd be the last person on earth to defend debian or systemd-boot that has turned linux into a garage project, but could it be that you are booting the image in legacy/bios mode and attempt an EFI installation? This is hackish to do since /sys/.../efi.. doesn't exist.
If you insure you are booting in efi mode then it should work out. If not chroot into the installation and follow the procedure of installing the bootloader manually.
