Brinkmann vs TW Acustic

Was wondering how these two German manufacturers compare.
Bardo vs Raven One
Oasis vs Raven GT
LaGrange vs Raven AC
Is there a unique sound signature that goes up with the range? Which is a better value? (i.e. maybe the Oasis is better than the Raven AC)
Have heard both in show conditions, but could not pin-point their contribution to the end result as the rest of the system was unfamiliar as well.
