The SRT Dodge Viper hasn't been doing so well recently, despite its nearly complete ground-up redesign. It's fast, brash, light, and raw, and is seemingly what everyone on Jalopnik wants: a supercar with a manual gearbox and the minimum number of nannies required by US law. The Porsche 991 Turbo S is the exact opposite, so much so that we question if it's actually a sports car at all. But which would we rather have? Which would you rather have?
