LLC's are usually the cheapest and easiest to set up especially for an individual. The LLC does exactly that. Limits the liability to the corporate entity. I don't think a dba does this. If any of your products incurs liability, the assets from the entire parent are on the line automatically. Lawyers always try to get through the corporate barrier and get at your personal assets, or connect your companies to get at them all at once. (This even happened in the tiny trademark case I was involved in) Having this done, and done right, its a big impediment to that happening. Don't mix your accounts, pay yourself a salary from each company and keep your papers in order.
