Yes, they both have an experimental airworthiness certificate, but when the FAA issues an experimental certificate, it comes with operating limitations (technically part of the airworthiness cert). The operating limitations you get depend on the specifics of the aircraft.

The more dangerous the plane is to people on the ground, the more severe the limitations. For example for the really dangerous ones, they'll give you a limitation of "Flight over a densely populated area or in a congested airway is prohibited."
