2006 GTO(Black or 2006 G35(black)?

I been thinking about getting a car for the past couple of months i have found 2 cars GTO and G35 i can't decide what to get there both black same miles but i never really had a Pontiac or Infinity so I don't know what car is better on performance or more dependable ....There both about the same price except for couple or dollars. The GTO has about 75,000 miles and the G35 78,00
