Mild/ medium is good for chili and for Mexican food where youd expect spices or heat, sharp or Xtra sharp is good for sandwiches, burgers, grilled cheese, etc. Seems to melt into bread without making it soggy. Mild or medium can be used with bread but expect it to make the bread oily in my experience.
