I have tried most of the combinations and others, not listed. It really does not matter, if you are finishing on a 12k Super Stone and or a SG20. I usually mix the 1-12k stones, with a variety of stone, almost daily and there is no difference on the finished edge.
If you are going to jump to a natural finisher the 8K, Naniwa old Snow White Junpaku, is a nice pre-finish stone, but not, that much nicer than a Norton 8k that it would make, that much of a difference. But if you finish on a 12k, higher or natural, then it makes no difference.
Mix and match makers, as long as, they are quality stones. The low grit stones don’t matter, especially if you are not pro-honing.
What matters is setting a bevel fully, on an 800 - 4k, and finishing the edge as straight as possible. Technique and experience.
Hone a thousand razors, with the progression you have, then decide.
