They all have their advantages and uses.
I really like manifolds to maximize yield and maintain an even canopy.
Scrogs are good if you have vertical space limits as @Locrain99 suggests. You certainly need to consider that along with the lights you plan to use. There isn't going to be a lot of vertical space to grow your plants. ...My plants wouldn't fit in there, they barely fit in my 80" tent. I think you might still be able to do manifolds or other topping methods, but Scrog would be advised and then you're talking 2 maybe 3 plants max.
One way or the other, you will have to train the plants to maximize your yield in that space. Be sure to read all of those tutorials, I am sort of assuming that you already did.
