This is completely subjective and a matter of opinion, however my opinion would be that they're both good quality games. They both have their own advantages, modern warfare 2 has much better perks and more personalisation, however modern warfare 1 has better maps and better guns, overall i'd say only you can answer the question, but my experience would say COD 4
