That depends on what you mean by efficiency. The hybrid is going to be more fuel efficient since the fuel is converted to more useful energy...that being moving the vehicle from point A to B. However, it may not be more cost efficient if the cost of fuel is not enough to make up for the added cost of buying a hybrid. And that is from the car owner's perspective. Efficiency for a societal perspective is entirely different, taking the costs of production and disposal into consideration, and what energy sources are used to produce the vehicle.
There's also the fact we tend to use energy sources more efficiently the more we use them. ICE certainly have, and you could make an argument that looking at electric motors is going to slow progress in ICE. As well, we surely would be much further along with EVs if hard started developing them decades ago.
And of course, if efficiency really was all that mattered, then we all should be walking, riding bikes or staying home, but practicality and other things also matter obviously. The point is that I don't think these are simple questions that you can only look at from one angle. Certain vehicles are going to make sense for certain people in certain situations. Maybe one day we'll invent Mr Fusion and won't have any more worries about energy.
