Sorry, I got confused between this thread and my RC thread.
Here is the picture I was refering to:
I don't believe I 'need' better media, but this media would definately be less prone to clogging over time, due to detritus and other floaties such as dust from the tank water getting caught up in the reactor. I would guess that it would reduce the chance of having 'pockets' of stagnant water that may cause the production of H2S as well. (less of a channeling effect) I don't plan to switch to this media quite yet, perhaps a few months down the road once my nitrates are zero... we'll see.
