DUB versus SUB: Which is superior?

"Samurai Champloo" - Example
of good English dubbing

It's the age-old question... Ok, maybe it's not quite that epic, but it's definitely been debated since anime began its migration from East to West.

Obviously, most Americans do not speak Japanese.  Thus, the dilemma arises when distribution companies must decide how to market their product to American viewers.  Do you leave it as is, with the addition of subtitles (Henceforth referred to as "sub")?  Or, do you hire a whole cast of voice actors to perform the anime in English (Henceforth called "dub")?  Here are the pros and cons of each.

Anime Review: "Strait Jacket"

Not just for straight jackets...
(there's a pun here)

Synopsis

Strait Jacket is set an alternate history where magic was proven to exist in the year 1899. The use of sorcery spread throughout society and changed the social and technological development of the world.

It was quickly discovered that abuse/overuse of magic can lead to the sorcerer being turned into a hideous, crazed abomination, generally referred to as a Demon. Demons have the undesirable characteristic of slaughtering anyone and everyone in their vicinity. Seen as a tool, a terrorist group - the Ottoman Organization - starts using Demons to deliver coordinated mayhem.

Anime Review: "Aquarion"

A cast of interesting characters
makes Aquarion a fun story

Synopsis

Set sometime in the future, it is 11 years after "The Great Catastophe," a disaster of unknown origin that has destroyed much of the planet and its inhabitants. Following the destruction, an ancient race of technologically-advanced winged humanoids, called Shadow Angels, has been awakened after a 12,000 year slumber in their city of Atlandia. The Shadow Angels view humans ("The Wingless Ones") as cattle, harvesting them for their prana (life force). Prana serves as nutrition for the legendary Tree of Life. The Shadow Angels facilitate their harvesting via large vessels called Harvest Beasts, which are closely guarded by sentient mecha called Cherubim Soldiers. Ordinary weapons prove ineffective, and humanity quickly falls into chaos and fear.
