yes i would prefer the pvc style system for a few reasons...
first of all trying to clean out all the pots and rocks after each grow is a huge pain in my ass.. with a pvc system simply run a strong dose of clearex and h202 followed by some enzymes and you are set for your next grow.
secondly, you wouldnt have to worry about the flow to each individual plant because instead of having 85 tubes to fuck with and check, you only have one large one.
third, although root mass is not a big deal in this kind of system, you are still limiting the root mass growth by having individual containers.. in a pvc style system you basically give the plants unlimited root potential, so once they have enough they will just stop growing em..
the problems i can forsee with the pvc style system is that if you get any kind of root disease it will be nearly impossible to remove any particular infected plant due to the fact that they will all be intertwined.. also i could see the possibility that if your nute solituion is not strong enough, the plants at the end of the pvc could in theory recieve less nutes than the ones at the top of the system.. having a strong nute mix will ensure this will not happen. i could also see the possibility that if your plants became too big and healthy (if there is such a thing) that if you do not design your system well, that you could end up having roots that build up in corners, and could slow if not stop the flow of nutes.
all these problems can be overcome with some foreward thought and planning.. its all about making the better mouse trap.
