Different drivers prefer different handling traits. The best drivers are able to be quick in various cars and can drive around different traits to a degree. They also are able to adapt their driving to what the car requires. The current cars on the current tyres are very different to the cars and tyres back in 2007, for example. They will need different handling by the drivers but the drivers will still have a "sweet spot" where they want the car to be, in terms of handling.
That Hamilton is quick in the current cars and was quick in 2007 suggests he is able to adapt and be quick whatever. But he will still have a comfortable "sweet spot" that he would choose if he could.
