Better to form LLC in South Dakota or in Wyoming/Delaware?

If your business operates in South Dakota, cheapest is forming LLC in South Dakota. If you operate in another state but register the LLC in Wyoming/Delaware, you must register as ‘foreign LLC’ in your operating state — paying both fees. Wyoming/Delaware only makes sense for passive LLCs (rentals, investments, holding companies).
