General advice on which OS (Debian or PureOS) *I* should choose?

Thanks for coming back to me @Quarnero.

@pseud

is there a /etc/apt/sources.list I can drop into or merge with mine to ease the side-grade?

Yes there is, but you are not to be allowed (for your own good) to have two main repositories active under one healthy OS (either Debian one or PureOS one).

What about the use of ‘pinning’ discussed here https://forums.puri.sm/t/pureos-to-debian-how-do-i-get-back-to-pureos/7518/4
I’ve used a similar process with CentOS, dnf and the priority variable on my home server to stay with the Stream repos while maintaining my kernel on the cenosplus repo and it’s worked very well.
