Which is better squat or lunge?

A lunge and squat are both basically the same. A lunge is working both your front and back leg hamstrings a swell as your balance. A squat works your upper leg hamstring. But not your balance. But if you do the same amount of squats as lunges then you would get the same work out because you have both your legs powering you to get up, but you do twice as many lunges.
