It depends on your driving style and what you plan on doing with your car. If you're driving mostly freeway and highway, go for the V12's. But if you plan on hitting the track once in awhile or if you're pushing a lot of power, go for the PSS's. No point in buying really expensive tires if you're not going to really use the most performance out of them. For most people, the Hankook V12's should be efficient enough and I'm sure you'll be really happy with them (depending on your style driving of course)
