I've got an SBE II... actually it's the gun my wife shoots. I'm not an auto guy, but i've got both the SBE and the SBE II. They are slick guns. The recoil is lighter than any of my pumps and they weigh less. That fancy recoil tech on the SBE II works, sorta. With the 3 1/2" turkey loads it'll still make your eyes water, but it's far better than my 870.
The brownings are heavier and seem to be less reliable. I've guided guys who shoot them and, like all autos, they are fair weather guns. Figure in dogs, water, freezing temps, and mud, and you'll get misfires and hang-ups.
The thing I like about the Brownings is their looks. They're much more attractive than the synthetic benellis.
