LLC will limit your liabilities as the name suggests; hence if you want to be protect your personal property from being sued then go this way. Ofcourse it is more complicated than that, but that's the gist.
To be registered as LLC, you have to file different paperworks and pay different dues to the state and Fed. Keep those expenses in mind (such as registered agent, state filing and operating fees etc). Internet is filled with information on LLC, I recommend doing further research before digging in.
