From the document linked below, 10 top benefits, I found these two quite interesting:

"1. The Corporate Law Expertise Of The Delaware Court of Chancery Delaware has a highly respected court that focuses on corporate issues – the Court of Chancery. Because of this specialization, the Court of Chancery has a great deal of expertise and familiarity in resolving complex corporate disputes. No corporation wants to be involved in litigation, but if you are it is reassuring to know the dispute will be resolved by a very knowledgeable judge who is sophisticated in resolving corporate law matters.

1. There Are Greater Privacy Protections in Delaware Than Some Other States. Delaware does not require officer or director names to be disclosed on formation documents. This provides a layer of anonymity that is not available in some states."

Court disputes resolved by ONE judge, no jury. And anonymous officers.
