There's not a straight forward answer. It depends on your driving goals. Things to consider...your driving style, your local weather conditions, how you use your car, how many miles a year you drive, do you want a good rain tire/snow tire/performance tire/ultra smooth ride (like my OEMS)/smooth ride...lot's of give and take. For example:
My car came with Firestone Destination LE 2s which some people really like, I found them too mushy/bouncy, not a performance oriented tire at all. I wanted more precise handling, shorter stopping distance (particularly in the rain), better cornering and I was willing to give up MPGs to get it. And I was looking for the same thing in a winter tire and was willing to give up ultimate deep snow performance (the Seattle area doesn't tend to get harsh winters) to get it. I choose Pirelli P Zero All Season Plus for summer, a 3.5 season tire and Hankook Winter i*cept evo2 for winter, a 3 season tire.
Cheers,
