Hmmm...I dunno ;)
Usually, SuSE isn't the first in line when it comes to new versions of GCC. They like to stay safe when it comes to something so important.
Yes, we bicker a lot about compilers here, but sometimes one just works better than the other...

PGCC is a subset and list of optimizations to EGCS, much the same as EGCS is a subset and list of optimizations to GCC. I will warn you that you *almost*always* trade stability for speed. How fast do you want to go? :)
