First, 52-42-30 is no longer the standard, most new triples have a 39 middle ring.
Whichever works better is dependent on the derailleur geometry, not the shifter.
Front derailleurs are designed to work best with a particular set of chainrings and chain width. Any departure from the design may reduce the deraileur's performance. The differences are in the rail depths and cage width.
A triple front shifter needs to have click stops (detents) that are compatible with the crankset. This does NOT mean that there must be two stops for a double or three steps for a triple. It simply means that there needs to be stops that will work. Shimano road triple shifters have 4 main stops and usually a trim stop for the smallest chainring. I am not familiar with your particular shifters.
