Gregsalyers -- Each state has slightly different requirements and slightly different protections for various types of entities, so while I can't give you a definitive answer to that question, you attorney should be able to.
In general, LLCs tend to offer the same protections as a corporation with much less hassle and paperwork required. They also don't have to make their earnings and other records public, while corporations generally do.
When advising clients, I generally start with an LLC if there are a small number of owners who are active in the company and a corporation if there are to be stock holders and/or "silent" partners. This, however, is only a starting point. There are other considerations that are too numerous to go into here.
As far as taxes go, you can choose to have an LLC taxed in the same manner as an S corp, so there is no difference there.
So, ask your attorney why he recommends an S corp. Ask why it would be better for you than an LLC. Ask him about the requirements and benefits of each. They should be able to give you simple, understandable answers.
I know that is not a clear, straightforward answer but, as I said, I can't really address your specific situation over the Internet. I hope you find the information at least somewhat helpful.
