If my opinion counts, I like both dubs and subs. I have a preference for dubs, though, as the subs occasionally look too literal. And I usually care more about the graphics than the voices when watching an animated show, so I can't really detect passionate voice actors. Sorry.
I've only ever watched/read Death Note and, when I was about 8 years old, two seasons of the dubbed version of Dinosaur King. I still watch it occasionally for the sheer comic relief factor (and the awesome chibi dinosaurs).
