IMO, much of this depends on the speaker match. Given a particular speaker, the ARC may sound better than the Rogue, and the opposite may be true for another speaker.
Perhaps it would be valuable if those with listening experience with the amps also specified the speakers they own or heard, including sensitivity, nominal impedance and minimum impedance specs.
