I've owned a Browning BPS, as well as my two Benelli Supernovas and I can tell you that either are excellent shotguns. The BPS is a bottom load and eject which is helpful in a duck blind, but not as easy for trap shooting. I'm a lefty and don't find the Benelli any more difficult than the Browning in this regard. I liked the BPS, but love the Benelli.
Also, the price difference between a pump and a semi is not a big deal for me, but I do like the maintenance-free aspect of the pump. Well, minimal-maintenance, I suppose I should say. I just pull a Bore-Snake through after use and that's about it.
