Personally, I prefer using quotation marks " " for proper dialogue since I want to improve my grammar and writing style. Of course, different cultures may write it differently (even how british vs american use quotation marks), but since I'm following more under the american writing style, I'm gonna be using "". ( ) to me are not really for dialogue but to emphasize certain things, etc.
Other than that, the only time I might consider something different would be using :, because it feels easier to read dialogue. It makes one feel like one is reading a script. However, I feel it would be kinda awkward on how to try to incorporate scenes mixed in with dialogue (do put what they do before or after the dialogue) and not sure if it'll even flow smooth.
Mark: And this is how I'm gonna die. I'm gonna die by idiocy.
Sam: Not today on my watch. (Pulls out a box with a bright big red button on it).
Mark: (Looks at him, dread creeping up his neck) What the hell is that?
Sam: Instant re-do button! (proudly smiles). Only one in the universe, just hit a button and re-do and all good.
Mark: Wait no! What if you reset the whole the universe, including our world from scratch? Don't you even think about it, you moron-
Sam: (Slams hand down on the button).
Whoosh.
I'll probably stick to using "" for now, unless I'm too lazy or I'm trying to write something like characters doing an im/messaging type of thing.
