The total muscle mass of involvement with deadlifts is higher than squats because of the lever used by your arms (whereas you support the bar with your back in the squat, the same muscles that keep the bar close to you when deadlifting). Rather than someone interpret this as "do deadlifts over squats" I'd say "do both because they're both great for your body if executed with proper form and weight."
