I had to vote other as I keep a lot in the sump and only what I need in the display to make the aquascape I need for the animals. I have always overloaded my sump with rock. I have done this in my sps system, gorg, and now my softie/nem system. I have never had many issues with stability of parameters, just the typical hair algae issue I have now (never been this bad in like 10 years).
Because I keep so much in the sump, I always have spare live rock around for any small system or emergency situation for qt set up.
This is true for my large 210g display and my 40g/20g displays. I even use rubble in my 6g system in the HOB filter.
