Horsepower and Camry do not go together. a 10 horsepower difference between models is not anything you would really notice. The Camry is not built for performance. It is built to be a reliable, comfortable and relatively affordable family car. Speed and performance is the least of Toyota's concerns on that car.
The power is fine just to go from point a to point b. It will do just fine on the highway, but you are not going to win any races. The 179 horsepower SE version does 0-60mph in 8.3 seconds. To compare, a 2010 Toyota Sienna Minivan will do 0-60mph in 7 seconds.
