Since you live in Michigan, there is a good chance you endure many morning below the freezing mark, which includes late fall and early spring, so unless you only plan to drive your car when the temps are 50F and above, I would look into All-Season tires only, as summer tires can crack at low temps and provide less traction than all-seasons at the lower temps.
I just put a set of 255/45/19 Michelin Pilot Sport A/S 3's on my car, and I'm ecstatic. These tires balanced up with less weight than the factory Pirelli P Zero's on the Brembo wheels, ride extremely smooth (not mushy smooth, flat as glass smooth), no steering wheel vibration, have great initial turn-in, and have less deflection being transmitted into the chassis when hitting pavement or bridge seams. Since they are new, of course they have good traction and are quiet, but since these are not summer tires (which usually have one single row of solid rubber), I expect they will always be quieter than multiple summer rubber tires I've been driving on for the last 2-years. These cost more than the average A/S tire, but so far, they are proving to be worth it.
As for summer tires, I've had the Continental DW Extreme's on my 2011 GT. These lasted about 20k miles (mostly highway miles), had good traction above 50F, tires balanced initially, rode well, and are priced well as well. On the negative, after the tires were about 1/2 life, they started getting noticeably louder with road noise, and no amount of balancing would get rid of a slight steering wheel vibration. Another thing I noticed with the tires was a little loss of initial turn-in, cold-rubber flat spotting (meaning you felt a slight vibration until the tires warmed since the rubber molded flat while sitting overnight), and quick wearing of the shoulders.
The Michelin Pilot Super Sports are great tires from all the things I've read about them, and are probably the top of the premium summer rubber compound tires available at this time, providing some of the longest rated life as well.
