Michelins.
On the occasions when a car has come with something else, I've replaced then with Michelins when the time came. I've tried Firestone, Bridgestone, Dunlop, Goodyear, Viking, and in over 700k miles in 43 years have preferred the company of Mr Bibendum every time.
IMHO Primacy 3s are a better choice for the 9-5 than the PS3, so I disagree with Mark B there. Tried both for over 40k each on my 9-5, but each to his own.
One characteristic - good or bad, depending on your point of view, is there's a rapid fall-off in ride comfort as Michelins get near the end of their life. A warning that it'll be time to change soon.
