BUFFALO OR BISON.

The interesting bit:-

Differences in Physical characteristics.
Bison have a hairy fur coat on their body which grows thicker in the winters as a protection from the rugged environment they live. Buffaloes do not have thick fur.
Bison have very sharp horns which they use for their defense. A buffalo's horns aren't very sharp but are longer than a bison's.
Bison have a huge hump over the top of their front two legs which Buffaloes do not have.
Bison also have a thick beard that circles around their rib cage but Buffaloes do not have a thick beard.
A Bisons' temperament is associated with its rugged structure and it can be a very attacking animal when threatened, Buffalo, on the other hand is a peaceful animal. This is also the reason why it is domesticated.
Buffaloes grow upto 5 feet in size while Bison may grow to 6 feet.
Bison can run faster than Buffaloes.
Buffaloes can weigh between 800-1200 kgs while Bison can weigh up to 1400 kgs.
