I got Michelins on mine in NJ. Here are links where you can read reviews on each tire:
The Michelins are in a tire class called Grand Touring all-season at Tire Rack. Grand Touring All-Season tires are often used as Original Equipment and place more emphasis on handling and high-speed capabilities than Standard Touring tires. http://www.tirerack.com/tires/types/grandtour_as.jsp
The Bridgestones are in a tire class called Standard Touring all-season at Tire Rack. Standard Touring tires are typically available in the lower speed ratings and higher aspect ratio sizes and place more emphasis on ride comfort and treadwear than Grand Touring tires. http://www.tirerack.com/tires/types/touring.jsp
So, if you can believe Tire Rack editors the Michelins are for better handling and higher speed, but the Bridgestones should last longer and ride easier. It looks like the Michelins are a little more expensive at Tire Rack than the Bridgestones.
Link comparing the 2 tires:
The info at comparison link indicates the Michelins should last about 70% more miles than the Bridgestones, which doesn't match the tire categories the tires are in.
The other major difference is that the max tire pressure on a Bridgestone is 51 PSI while the max pressure on the Michelin is 44 PSI.
