I've experimented with both. Aeroponics is a LOT more complicated- you really need a high-pressure system if you want good results (fogponics with an ultrasonic humidifier doesn't work well enough). And a high pressure system has to worry about clogs in the nozzles, and it has more moving parts, and some of those parts need to be well sealed.... vs. hydroponics which can be as complicated as turning on and off an aquarium pump.
