The other reason it is done in EDT is that you get to have a jury trial, basically you can get layman off the street and argue it in front of them rather than have to follow the letter of the law.

This makes it who can argue the best. Whereas in Delaware where most suits are filed for big companies the judge with a lot of knowledge and business law experience handles the case and thus the letter of the law is followed which means you get an extremely fair trial.
