No, it's nothing like that. Businesses like Delaware because they can easily hire lawyers that know Delaware law, and those lawyers can say with a good degree of certainty that the law means X or Y, because many businesses before them have already settled the case law there.

This is not the case for every state. In some states, your specific business legal concern might be something that is not clearly outlined under the text of the law, and there may be a complete lack of case law to guide your lawyer.

TL;DR: lawyers in Delaware are more likely to answer "yes" or "no" rather than "maybe" to your business law question.
