There are thousands of varieties of hot pepper in the world, varying in heat and flavor profile.  Some, like a Poblano, are mild and used mostly for flavor.  Some, like habaneros or Scotch bonnets, have a strong kick.  There is an entire industry around outdoing the current hottest pepper with an even hotter one.
