When we juxtapose two things and compare them i.e 'Xbox and PS4 ; how do they compare?' are we looking for which one is better? Somewhat by the same token, when we say 'Mastercard and Visa card ; how do they contrast' what are we insinuating ?
I saw that compare doesn't necessarily mean that we look at similarities between the two/more things , so why use 'contrast' at all ?
