I have no experience with the Guerini, but do with the other two. I favor the Beretta over the Browning. I have seen too many Brownings with steel frames loosen, to the point that they open themselves after the first shot, to ever want to try one of their alloy guns.

I have over 10,000 rounds through my SP II with nary a hiccup. I just don't think there is a better production hunting/clays O/U on the market than the 687 series Berettas.
