The biggest difference between the too is operator and his/her knowledge. 2 different ways to skin a cat but looking for the same end results. fundamentally there different and going to be run different so if you understand one way more so then the other you'll do better with the one you know, but regardless mo matter which one you run if your not producing a high brix, high terp/ cannabinoid plant you have work to do. just because your plant looks good your buds look nice etc doesn't mean the end product is, the proof is in the brix, terp/ cannabinoid etc.
Also its not just about the system, there is so many other other factors that go into play, environment, lighting, temps, medium nutrients and ratio's, defol techniques etc, the list goes on, they all have a hand in your final product.
I ran RDWC for years, I ran it sterile, where i added microbes and enzymes, and I also ran it in very clean environment with straight well water where I never added nothing but nutes, and each one always ran as good as my weakest link.
From my experience if all your limiting factors were dialed in as optimal as you could get them, 66 F to 74 F made very little difference in growth or anything really, applied nutrients/ ratio's alone played a much bigger role in plant morphology, health, brix terp etc. environment, lighting temps, defoliation, medium etc play a big part in nutrient ratio's
personally for me I'd rather run sterile and spray fulvic, kelp's etc.
