Theoretically they are not exactly the same at all....
Maybe a bit more detailed question from the start would stop arguing...
The question should be based on if YOU were driving the vehicle, what would be worse for YOU...
If you hit an immovable object at 100km/h, the force/inertia/momentum of you inside the vehicle experience G forces and negative G forces (as the car would be pushed back from the object once it has hit it)...
You would experience MORE G force and negative G force from 2 x objects that has the same force/inertia/momentum when they impact each other(instead of just one with the previous example)...
But, the bottom line answer to the question is that I would rather not be involved in either scenario - and continue to order my drink at the bar thank you sir....
