I am a sales rep who receives a company car every two years. I started with a Nissan Altima 2.5 S and liked it at first. The model I had was only a 4 cylinder and had plenty of power on the interstates. I drive alot of miles so the interior attributes are important. The radio system was subpar. It was difficult to find a channel quickly and trying to see the display because of the small display. The most annoying thing was to try to turn an inside light on from the dashboard and there was no way to set it up to turn on automatically when you enter the car. If there was a way it was hard for me to figure it out. My fellow sales rep and I both had the plastic bottom plate come loose when we accidentally parked over a concrete slab at parking lots. It was flimsy but getting under the car and inserting a new screw fixed the problem. With the Altima, I felt I sat down rather than looking up over the road.
I just received a Camry LE two weeks ago and love it. The interior seems a lot larger than the Altima. The inside light can be set to go on when you enter the car. Turning it on is also easy while trying to read a map at night. You sit alot higher over the road. The radio has large viewable numbers/letters and easy to use.
The Camry is also a 4 Cylinder but the Altima had a bit more power on the road. However, the Camry Camry dampens the outside noise much more.
I have been lucky to try both cars and have to say that the Camry is a much better car to take long trips in.
