Great post. However, I will add my opinion about Debian Sid and its lineage: just don’t use them for production. Sid is an unstable distribution that looks like a rolling release distribution and most of the time it’s fine, but it is fundamentally different since it’s okay if it gets broken.
I’m guessing the idea behind Siduction is to use this rollback functionality to counter its innate instability, but with solid alternatives like openSUSE or the already installed Linux Mint + Timeshift, I wouldn’t recommend Siduction. Also, Manjaro is unstable by design, wouldn’t recommend that one either.
