What would be most beneficial for my credit?

I have one credit card with a balance of $2254 and $3545 left to use on the card. I also have another credit card through my bank with a balance of $5417 and $2082 available to use. I want to consolidate the first credit card to my bank credit card in a few months because the interest rate is lower. Would it be more beneficial to transfer the balance from the first one to the second one and only have one credit card payment or should I pay them off separately to help my credit score? Thanks!
