Get a Hellcat and ZL1
But seriously, depends on what you plan on doing with the car. If you like a nice big comfortable cruiser with plenty of room, that is also a straight line rocket, Hellcat. If you're into drag racing and modding your car for more power, Hellcat. If you're into curvy roads or racing on a circuit, auto-x etc, ZL1. If you like a tighter cockpit with that "fighter jet" feel, ZL1.
