You do have to track how much you put on each card each month, though. The 6% BCP has a yearly limit but the 5% Sallie Mae has a monthly limit. Unless you know exactly how much you will spend on groceries in each month for the next year, it can be hard to decide when to use each one (if the goal is to maximize every dollar of cash back).
If you're going to go through both spending limits, the mathematically rational option would be to put the first $250 each month on Sallie Mae and then switch to BCP to 'soak up' any spikes in grocery spending. It could be annoying, though, to go over $250 on the Sallie Mae and then have leftover capacity on the BCP at the end of the year.
Sallie Mae has no AF, so it's hard to wrong having it. The main issue is that you have to switch between the cards a little every month for Sallie Mae to have a real effect - and that may involve more micromanagement than is desired.
