Best for who?
There are at least 54 other jurisdictions within the US alone that have incorporation statutes. Those legislatures and courts haven’t all sat still for the last 30 years, they compete directly with Delaware, other countries and each other.
Delaware’s Court of Chancery, a business court, is replicated is some other states, Wyoming has one. Whether a jurisdiction has that or not, a huuuge benefit is that outside of Delaware you can relitigate cases and argue for the exact opposite outcome as to whatever case law Delaware judges are bound by.
Back to the “for who” question, some things benefit your investors more than you.
Its all a reading comprehension problem.
Currently I like South Dakota for Trusts, Wyoming for LLCs, I still like Delaware for C-Corps, and Delaware for non-profit corporations
I form LLCs the most
