The main difference between Log functions and System_printf is that Log functions have fixed execution time regardless of the number and type of parameter. Here is more info.

Two ILogger service providers are included in the xdc.runtime package:

LoggerBuf - copies events to a circular buffer in a fixed small number of cycles and is suitable for real-time high-frequency event sources, and
LoggerSys - outputs events as they occur using System_printf() and is suitable for initial development or low-rate non-real-time event sources.
