Difference between rsync -r S1 S2 T and cp -r S1 S2 T

Dunno for sure, but I'd expect differences if S1 is /dev

Simple case, a copy is just a copy.
Edge cases, there's lot of room for differences in exactly
what happens when things are not exactly perfect. 
Many times I use rsync because I know what it does and
I'm not exactly sure what cp will do.
These differences increase in importance with distance
between the source and destination.
