This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information. If this question can be reworded to fit the rules in the help center, please edit the question.
"Comparison between" is used when you are listing choices to be compared- as in, "We can make a comparison between Toyotas and Volkswagons."
"Comparison for" is used when articulating the intent of the comparison- as in, "We can compare these two answers for similarities."
So, "what's being compared" vs "what you're looking for during the comparison"
