rcs or sccs: which is better?

[Tim Smith]

OH GOD! NOT THE SCCS VS RCS THING AGAIN!!! ARRRRGGGGGGGHHHHHH!!!!!!!!

This is a pre-flame.  Some idiot is going to make the claim that SCCS stores
the first version of the file, plus diffs to make the later versions, and
hence is slow to recover later versions.  THEY ARE WRONG!  End-of-pre-flame.
