Cant really say which hydro system is the best, it really depends on which you're more comfortable with and usually your first hydro system will be the one your comfortable with. I currently own a ebb n flow system with a 3x3 tray and a 25 gal res, using gh 3 part nutes. The maint. on that hydro system is pretty minimal, the only time i actually do some work on that particular system is when i change out my res, wash down the res, and add my distillies and nutes. All in all, very easy to use. If you're interested in a hydro system then do your homework and find which will fit you and most importantly your grow room size. Ebb n flow takes up some space by height since i had to build my own tent to support my heavy 600 watt light fixture. If you dont have much space then an ebb n flow system is not for you. If you want to build one then all you need is a rubbermaid container with a lid, a tray to support your plants (i just ended up buying a actual ebb n flow tray), a water timer which is like +20 us, hoses (very cheap like under 5 dollars cheap), the fill and drain nozzles (hydro store 3 us each), and a pump timer (like 20 us dollars, you dont really need a fancy one like a digital, the regular dial timers work just as fine so dont waste your money), and hose clamps which run about 50 cents.
