I agree. I don't think it's an absolute rule that subs are better than dubs. I mean, Cowboy Bebop is a popular example that directly refutes it, but it is kind of a special case given that it is heavily oriented towards western pop culture. It's the same for The Big O, which obviously owes a lot to film noir. I also agree with Dave, it's not so easy for me to watch stuff I first encountered in Eng dub in the original Japanese, though it can be interesting to compare the two. At the same time, I do feel like the Japanese is more natural sounding in most anime, especially since a lot of it deals directly with Japanese culture and is in some cases inspired design-wise by traditional Japanese art and theatre.
