Hmmmm.... er,... a roll rate in excess of 180 degrees a second probably would beat the A320, and we have recorded that off a B737 before today. Now, the aircraft was aerodynamically stalled and with a substantial yaw rate, but... there you go.
Then again, the A320 has achieved some wild roll rates when the flight control laws got messed up a bit too, with the gain of the spoilers being incorrect for the TE flap configuration, the dreaded OEB 117 badness. Now it only got about 100 deg/sec on that, but still quite surprising.
just to put oil on the fire, the A320/330 have pretty nice controls, compared to the B737, most planes do. Heck even the B777 while possibly BAC's nicest equipment to date is not as nice on the control laws (in normal law) as the A330. System logic/crew interface is something altogether different.... 
. whatever floats your boat.
