That's easy.. A big big dish prevents detonation. A big big dome is great for horsepower...... Just kidding.
In a perfect world where the chamber can be made small without sacrificing flow, a small reverse dome is the best as the perimeter reflects combustion back into the center momentarily for a more complete combustion. In the real world, Hit the max compression ratio your fuel will withstand. There are some dome designs that do a very good job of enhancing flow around the valve and enhancing combustion.
