Well, I figured I had to say something about my love of all the JMB-designed shotguns - and I couldn't exactly figure which one would be the "top dog".
Stevens 520 - the original "double hump" - would be my number one, followed by my Savage 720 or Remington 11 AKA Browning Auto-5.
The Stevens 520A, 620A, 620 are all great too - same break-down gun at the core. Here are a pair of my 520's.
