the aesthetics issue is going to depend on the individual, but grow out room for corals is something to consider as these animals will just keep expanding - think in terms of how you want it to look a few years from now. And the flow issue is not a minor one - dead flow areas are more prone to diatom and cyanobacteria outbreaks.
also, the filtration benefit is not so much a function of how much rock in terms of size and weight, but surface area. porous, open rock will do more in terms of filtration than its equivalent in area and weight
