I think the bottom line is as is evident here, there are some very good semi-auto's and it often comes down to one's experience and preferences. And those can change too as experience grows and different models appear.
I'll admit to biases against most American made shotguns for several reasons, with a few exceptions, including the semi-autos -- there is no close competition here for the Big Two from Italy IMO but that's what makes a horse race.
Good luck with your choice.
