It all depends on your situation:

loan amount, rate, tax bracket, rental property at net income or loss, other tax load (property tax on primary), of course MAGI, etc.

Either way, the effect is going to be fairly small.

You are basically talking about a $100 plus or minus difference, not even quite enough to pay for a decent dinner for a family of 4 these days; so it is probably not worth splitting your hair to try to figure out which way is better.
