The "perp walk" alone will be priceless.
I vote "alive" for entertainment reasons.
If he's taken alive, the Rats and the media will demand that he be turned over to the ICC. The "court" will allow Saddam and Ramsey Clark to turn the "trial" into a big global Bush-bash, indct Pres. Bush for war crimes, and then turn Saddam loose.
And if they can't pull this off, it will be a trial in the Federal courts, and we can watch Johnny Cochran and friends, with massive support from every leftist organization known, turn that triala into a circus, like the Moussaui trial.
Make sure he's dead - if he's not killed while fighting being taken into custody, then he needs to die while "trying to escape". The left can wail and carry on all they want, but if Saddam's worm food there's nothing they can do to bring him back again.
