Well, I use ebb and flow in veg, and drip in flowering....
I don't really think either is superior for each other. The drip system can be more troublesome, such as drippers plugging up, but it all depends on how you do things, what kind of media you are using and your feeding times. I use strictly hydroton for media in both places. I also really have a 'dripper system' without drippers, because I just use the 1/4" tube, and stick it directly into the hydroton.... so I have no plugged drippers. But if you try that you cannot do it unless you use no media or just hydroton. Both work fine for me!
