Is Fidelity offered Turbo Tax worth it over FreeTaxUSA

I was using FreeTaxUSA last few years and was quite happy with price/value offering and noticed for the first time Fidelity Turbo Tax Premier Free offer in my account dashboard. Is it really worth it or should I stick with the "little guy" FreeTaxUSA? Is Turbo Tax really free (states for me "Receive a free federal and state tax return") or there are some gotchas?

As a side note, I am always suspicious of big guys and was more than happy to pay fair price for upstart competition like FreeTaxUSA, but free is free right? Any experiences to share?
