  unclassified "original" meaning was "for through traffic". Which is
"better", or in normal terminology - "higher in the road network
hierarchy".
  As for the name "unclassified". Both residential and unclassified
are roads which do not have national reference numbers/classification.

  If unclassified and residential would be identical, what would be
the reason to tag such roads differently?

P.S. Name "residential" is kind of misleading. Because of the lack of
highway type for large arteries in industrial/commercial zones,
residential is used for that in order not to have just "service"
roads, and not to tag them "unclassified" as they are not for
through/important/high traffic.
