580EX, no question. It's the most powerful, most efficient, easiest to use flash for Canon. The single button head rotate is great, the biggest advantage over the 550EX.
tim - maybe it's my science background, but I get very antagonistic when somebody states inarguably as to what "the best" is.
580 isn't the best, but it's a good flash obviously.
A lot of photojournalists use Quantum flashes:
They are reported to be more consistent and the interface is very user friendly IMO
Are platform independent
The reflector can be removed and used as bare bulb
The reflector is a true parabolic one
You can use a snoot or a grid with it
You can fire it more often and it takes it, while canons overheat.
In comparison, the 580 is lacking.

You also need a battery, a canon adapter and a cable. Sold as a package they are about a grand.
You get what you pay for.
