Well, I'm like Layton, used to use sand, then fell under Bombers influence and became a BB fan. And there's good reasons for that.
BUT, after all the theorising is done, the bottom line to me is that the proof of a method is in the pudding.
I used to think I had pretty good corals but starting to think again I'm seeing better over and over, in other peoples tanks with sand.
Also many of the real stunning tanks we see pics of have sand, even DSB's, yet fantastic acros.
There is still much to learn, IMO, about how this all ties together.
