Both venison and Bison meat have soft and tender textures, so they can be a great alternative to red meats like beef or pork.  When it comes to taste, the two are very different. Venison has a wild taste but is much more delicate than Bison, which tends to be slightly gamier.  Bison also has a fuller body taste that unfolds in your mouth as you chew it, while venison steak is a simpler taste with slightly sweet tones.  Of course, taste preferences are highly subjective. Still, in my experience, venison has been a consistent winner with food reviewers due to its delicate flavor profile.
