That's on paper. In real world driving the the 2AZ-FE feels comfortable at high rpm, probably because it has a balance shaft to enhance smoothness. Also, in the real world, when driving a 2AZ-FE Camry you find your speed creeping up to 75-80 MPH even when you didn't intend to drive that fast. The Altima 2.5 4 cyl, doesn't have a personality like that. Instead, you have to consciously press the accelerator further to get the car to go that fast.
Some Nissan engines are really responsive however. Like the mighty Titan / Armada V8 which is a thrill to drive.
