It is your choice, depending on car performance, handling and most of your driving standard
There is not a single particular brand that is best. It all depends on your location, weather location, way of driving, and how much you usual carry in your vehicle. But normally, as long as you respect the proper tire pressure recommendations to your specific vehicle, you should be able to optimize your gas mileage.
Specifically to your question: the asymmetrical tread is best; because, it allows more easily for tire rotations. No flipping, dismount, re-balance etc.Rotations help with tread-life and noise reduction from irregular wear patterns. Which is best for your car does depend on use and environment.
