The Firestones look the coolest, IMHO.
I only know the Cooper Cobra from experience, so I can warn you that they really, really suck when the road is wet. And you don´t need to be in the pouring rain for them to get you in trouble, a slightly wet surface is enough.
My opinion is "DON`T (!!) buy them!!" I nearly got killed because of those Coopers when my car totally understeered and slid straight forward into the trajectory of bus while I was going around a bend at less than 20mph! Luckily the bus driver was able to stop.
That was the worst thing that happened but I´ve had numerous other situations with those tires.
Just saying..
