They are both good shotguns. Buy the one that fits and feels best to you.
There are so many good solid O/U's out there just take your time and make your choice.
I don't have an O/U but I liked the feel of the Berretta better.
I think that also, Berretta makes better auto-loaders, anybody see that XTrema2 video on Google?
Ok.. I don't know about the whole "higher class person" comment. You can get into a good lowered price over and under for around $500 (check out the mossberg or afew other brands that make them) but thats beside the point. I agree with the guy who said its like asking which is better "ford or chevy". Personally i'm a browning man but i've also never shot a beretta that i didn't like. I'm just gonna have to go with the browning because i grew up using a citori and i just bought one afew weeks ago. They are great feild guns.
