soil vs. hydroponic set up

Hello again...
So I got in an argument today with my friend about the methods of marijuana cultivation...He does not believe that marijuana grown in soil can be as potent and as good as marijuana grown in hydroponic set up...

PLZ take the following poll...so that i might prove my point to him....

they can both be grown just as effectivly its just a matter of personal preference

Some people say it tastes better if it has been grown in soil. Hydroponics/Areoponics will be quicker.

bioponics is the way forward, using an organic soil-less mixture with canna coco, and then to use organic nutes that are suitable for hydroponics, your going to get the same taste from soil but with the added benefits of hydro, the plants will grow quicker and if you do it right you should have a higher yield also. I dont know if the potency will be more by going hydro but i do know it wont be any less
