Turkey burgers have slightly less fat than a buffalo burger, I do believe that buffalo meat does have a higher amount of proteins and nutrients than that of turkey. Buffalo is more expensive.
Both are 98% fat free. Turkey 23. 5% protein, buffalo 21. 7%. Cholesterol is 60mg. in turkey where buffalo is 62 mg. Buffalo meat has 138 calories per 100g and turkey has 146 calories per 100g.
