Promix or Hydro?

Which is easier to maintain, promix or hydro? Im doing hydro right now but I am considering switching to pro mix, what are the pros and cons? thanks.

I use promix. I was considering switching to hydro but I dont have to worry about water leaks or clogged parts or failed pumps. I know unless I lose my arms my plants will get fed. I can sleep in peace knowing nothing is going to fail on me.

Also I just started using General Organics Nutrient Line, and they dont require PH adjustments, so it makes growing even easier. I just have to mix and feed, twice a week, and watch them grow.
