The dichotomy between the two brands is that Ferrari makes race cars that are street-driven, while Lamborghini makes fast street cars, with little or no thought for competition.
That said, truth is it doesn't matter. Horsepower is like immortality, money, or Jessica Alba - more people desire them than know what to do with them. Most of the people buying high performance sports cars can't come close to extracting a fraction of these cars' performance (hence the dwindling Enzo population). Anyone that's done a few track days has seen high performance metal spanked by Miatas, old BMW E30 325s and Porsche 944s with little more than suspension mods, racing brake pads - and skilled drivers.
Which is no big deal because most of these cars don't see the track anyway, and will come nowhere near their limits on the street, just the occasional straightline burst of speed on a deserted interstate. The majority are bought for their halo effect, the image they project, and the way they make people feel about themselves (part of our style, if you will). Even if you're not a Balboni or Rohrl, you can still get that frisson of excitement from owning, driving, and admiring a Lamborghini or Porsche.
