Big, huge, epic difference. A static baffle will block fluid transfer just as well as it retains it, and in a pumping system a static baffle will only promote pickup starvation rather than cure it as the pickup will deplete the reserve fluid immediately and the baffles will slow the refill.

This is also why designing fixes for fuel system starvation is NOT as easy as everyone thinks.
