i had one successful DWC grow with the hydro line. i did some OG Kush and Hindu Kush. they turned out great, really green grew like rockets. first time i've done hydro and only nutes i've used so cant give you a good comparison. have to adjust ph quite a bit usually 2x a day for first 3 days after res change then usually 1x per day. not sure if that is excessive. also some people complain about the grow big micro nute because the trace minerals dont completely dissolve in the water, but dont affect ppm and can be filtered with a pillow case if having issues with clogging, I never have. if you're going hydro i think they are a good place to start.
