It is always better from a power standpoint to release the most energy in the shortest time and the smallest space. (point in case: nuclear bomb)
This means release the most energy of the gases quickly using a burst disk in the smallest space. (compressed in chamber, not overflowing into barrel)

I beg to differ;
There were many experiments I did with a home-made Flamefront Accelerator. If you release most of the energy in the chamber, there is little to no energy left to push the spud down the barrel.
