Sprocket Ratio's......

Hey Guy's, Was just curiouse am in the process of sorting some sprockets and was just wondering, If going -1 on the front is the same as going +3 on the rear....Does it make any difference to performance to do one or the other????
The advantage of going -1 on the front is that I can use the chain I have
