I have! I have watched all of my animes dubbed and 
subbed. I'm well versed with subbed animes, 
(actually watched subbed first) but I tend to 
prefer the dubs for various reasons:
1. I like my own language fine. Japanese is pretty 
sounding and expressive, but I don't speak it, so 
I can only get so much out of it. Sure, I can 
register the emotion of what they are saying, but 
the novelty only goes so far for me. I have 
watched subbed anime before with anime pals that 
are sub junkies, and honestly, it gets old having 
them laugh at the 3 or 4 words they recognize, 
like baka and gomen ne. I'll readily admit that 
the "cheaper" anime companies like US Manga Corps, 
etc do haver some pretty crappy sounding dubs, but 
most of the shows I like are Pioneer or Bandai 
shows (Sunrise, AIC, etc)and the dubs on those 
sound just fine to me- in fact there are some very 
talented people voicing those shows that face 
cultural translation difficulties and the hatred 
of hardcore anime fans to make anime more 
accessible to the general public (and that's a 
good thing, too- the more customers for the anime 
that there are, the better chance that we get more 
of it!)I absolutely adore Wendee Lee.
2. If I am doing something while watching (I do 
artwork a lot) I don't miss meaning because I look 
away.
3.Family members and friends seem *much* more open 
to watching subbed anime.
4 And, as I said, if I am watching intently, I can 
pay more attention to the artwork, rather than 
reading as I watch.

I know some people are sub only, and that's cool 
if it suits you, but don't discount dubbing- it's 
not all crap like on Dragonball, (worst dubbing 
ever!) some of it's very good!
