The biggest thing I like about activation groups is for subprograms.  I
write a driver program that uses ACTGRP(*NEW), then write subprograms that
use ACTGRP(*CALLER) and don't set on LR.  These subprograms use *INZSR to do
setup, and then all information is carried through for the life of the
driver program.

However, once the driver program ends, all the subprograms are magically
"reset" and the next time they are called, they go straight to their *INZSR
routine.  For caching information and sharing data between subprograms, this
is absolutely the best thing since sliced bread.
