I'd have to see Larsen in a rally. He's a good circuit driver for sure. But circuit racing, where you're doing lap after lap after lap of exactly the same line and same surface, is a different skill set from rally where not only does the line vary from turn to turn, but the surface grip is constantly changing. That said, not all rally drivers adapt well to circuit racing and vice-versa. But if the criteria is all around driving skill, I'll stick with rally.
