They are different classes of car. The Camry is larger than the Corolla and will likely have a broader range of options available. It will also have lower gas mileage than the Corolla (both cars with gasoline engines). which car is better will be your decision based on your driving needs (interior space, ride, mix of city, highway driving etc) , and how much you wish to pay (both to buy the car and then to operate it (gas, insurance, maintenance etc).
You don't specify new or used,but this comparison should be useful regardless:
