Paying options in paypal

Should I change the paying option to be equal to (the day you subscribe is the day you pay, making it a 30 day content form regardless of if you subscribe in the 29th or the 2nd day.

Or let it stay as billing each 1st of every month.

I made a poll a long time ago about this when the feature first rolled out but I think enough time has passed to ask this question again and see how people feel.
