It's much easier to manage if you can
I did this because it's easier to keep up with them. However, if you do this and want a zero balance to report, there'll be a 3 or so day blackout where you won't want to use your cards between the due date and statement date. Hope that makes sense.
I have 3 credit cards.
I wouldn't have any different. I have all my accounts payment due date on the same day for a straight shot when making payments.
