It really won't matter, especially in a minivan where you probably won't notice an engine revving more freely, or a difference in noise/vibration, or a difference in fuel economy.
So really either would be fine.
I don't see Schaeffers in the stores I go to, never heard anything bad about it.
The important thing would be sticking to 5000 mile OCI's until your drivetrain warranty is up at 60,000 miles.
