I have tried both ways over years, and without a doubt it is easier to get the motor to idle and respond to throttle without any starting or other issues with the ported , above the plates connection.With the manifold vacuum the initial timing has to be retarded too much. I also use a pcv which also taps into manifold vacuum, so a bouncing pcv can cause fluctuations........I think...Just runs great with the ported connection.
