I'm an ebb n' flow guy. I like the ability to pull out the plants easily, move them around, turn them, etc. Ebb and flow is not usually used to grow big tall plants though. Your root space is contingent upon the size pots you use, and your root space effects the final yield and size of your plants. I am currently using 6x6x7 pots so the ideal plant size and flowering time is about 2-3 feet and 8 weeks for that size. I don't have that much space to grow, and I like smaller. high yielding plants. E n' F seems to work well for my setup. With DWC (bubbler) your plants remain pretty stationary. You can damage the roots and make a mess pretty easily if you move individual plants around. Sometimes you need to move plants around to get even light exposure. I am not knocking any style setup, I am just telling you about my experience with E n' F.
What's nice about DWC is you don't use too much medium (grow rocks, hydroton or similar). That's one less expense and care you won't have to endure. There's no flood schedule to worry about, no timed pump systems, no worry of clooged drains and stuff.
A nice thing about Ebb/Flow is the separate reservoir of nutrients in which you can make adjustments to it while your roots are not in contact with it. It makes for easy dumps and cleaning, easy topping off of water, supplements, and nutes.

It's your decision dude, I have never tried anything other than E/F so my experience is a little biased. If I had the room, I would try all types of systems to contrast and compare.

I guess I would recomend DWC (bubbler). It seems like it could be a little less challenging as a beginner, and there are many pics and threads in this board to get answers and ideas from.

Good luck!!!!!!!!
These are taken out of my ebb and flow for a routine cleaning. Three plants here almost done!!!!!
