The type of structure will depend upon a number of factors, which include the type of business to be conducted, the tax residency of the owners, whether you need employees, fixed assets, etc. An S corporation election can provide favorable tax treatment with respect to self employment taxes, however, the operating structure is much more stringent than a traditional LLC that is taxed as a single member LLC or a partnership. S corporations are only permitted to issue one class of stock, provide no tax basis in entity level liabilities, no step up in S corporation asset basis at death of the shareholder, among other considerations. Whether you decide to use an LLC, a corporation with an S election, or an LLC with an S corporation election, the decision should be made based upon your facts and circumstances, as well as your short and long term goals. I would recommend consulting with a tax adviser to discuss your various options.
