From a pure visual perspective, Lamborghini has some of the most celebrated modern sportscar designs ever made. Miura, Countach, Diablo and imo the Murcielago which is pretty much
perfect in my eyes. Some people claim the design is vulgar, but that's the intention. It's supposed to look like a raging hormonal aerodynamic deathtrap. The look of the cars was supposed to be inspired by bulls. The Reventon is cool, but it's just a novelty car. The shape is very similar to the Murcielago.
Ferrari has always been lacking visually imo, with the exeception of the testarossa. More reliable cars maybe, but they don't look half as spectacular as Lamborghinis.
The only gripe I have with Lamborghini is that they get referenced too much in bad rap music.
