Why would you even want dubs? Because you are too lazy to read? I don't really see the reason why, even if somebody would say "personal preference".
I direct your attention specifically to Baccano and Romeo x Juliet, two anime has far superior dubs, mainly because the Japanese can't properly apply Mafioso accents or Shakespearean English in their language, respectively. These two things NEED to be in English to be done perfectly.
Another common reason would be origins. Take myself, for instance. I mainly go for dubs because I grew up with them. It never was, and still isn't a matter of "too lazy to read". However, I voted for both, because these days, I always tend to find out which is better for an anime.
The most common reason, however, still is "because the dubs are just better", like in Fullmetal Alchemist, Trigun, Cowboy Bebop, Ghost in the Shell, and so on.
