Ra's is impressive in that he totally schooled Bruce. The train crashing is the only thing that saved his ass.
Oh, and Ror didn't get beaten up by cops. He got swarmed by cops, overwhelmed, etc... They didn't beat him up. The beating he took from Ozy goes beyond anything Bane can do, and he's strong/skilled/durable enough to take Bane down on his own, much less with help.
Actually, Ozy solos. Ror and Nite Owl scowl in the background.
