The 12 Valve Cummins is the simplest and often the most desirable because the fuel injection is fully manual. There are no electronics to malfunction. Performance upgrades are strictly mechanical.
The 24 Valve is often preferred because the engine offers electronic control over the injection and the 24 Valve head delivers better performance.
The Commonrail Cummins (2003+) offers the greatest control over fuel delivery and has the highest starting base HP. It also has great potential for HP upgrades and is the quietest engine.
