For tax purposes, an LLC can be treated exactly like an S-Corp, so unless you're planning on issuing stock, there's no significant difference between the two. As far as best combination of protection friendly and low filing fees, go with Nevada, Delaware, or Wyoming.
Another option to consider is a Series LLC. It basically allows you to have as many LLC's as you want, but only have to pay one filing fee. This makes it easier to get a bunch of EIN's, which means getting banned ain't no thang

Only 9 states recognize the Series LLC, Delaware and Nevada being among them.
Remember, if you live in 1 state and setup an LLC/S-Corp in another, open your bank accounts in the state where you setup. Otherwise, your home state could say that you operated out of it and charge you filing fees for your company.
