Kayvan has pointed out elsewhere some differences among all the other recent supercars, from the "budget/entry" 458, all the way to the hybrids P1, LaFerrari, etc., compared to the new GT. Biases aside, anyone with halfway normal eyesite should/would find the GT faaarr more aesthetically appealing than the others, especially the most recent NSX which seems to have the front end of a TLX and four year old Mazda 3's merger together. (For a car that was delayed seemingly forever, that's the best they could do? It may end up being a great car, but I think you could say they swung and missed on the visuals).
Ludwing Mies Van der Rohe said "God is in the details." Apparently, the GT designers were Believers, because all of the little things seem right, and the general package is outstanding. For a company nearly 10 years removed from making a supercar, Ford didn't miss a beat. And when one does compare it to the McLaren, let's face it, the oddly named ist iteration McLaren had a face only a designer's mother (or maybe Honda) could love.
Ford managed to capture the essence of the original GT40 in the headlights and fenders of the new GT, yet as radical as the rear of the car is, the single tail light/side recalls both the ist gen GT and the 05-06 cars.
