Alien aero or alien rdwc

I'm torn between which system to get. The aero is pretty much silent + no need for air pumps or water chiller. It seems like a no-brainer to go aero. I never suffer from power outages so I don't need to worry about that. The main thing is does aero create big yields like in dwc? Do you leave sprayers on constantly or is it the more you feed the bigger it gets or something
