I must admit a bias towards SxS's if I had to shot an O/U I probably wouldn't shot a shotgun that often...

In terms of snobbism, I've foudn the reverse to be true at least in the US. Go on any skeet field, or even a sporting clays course with a SxS and see the looks you get from the O/U and Semi-auto guys. I've gotten tired of the sneers, and the comments like, "Watcha doing with that old coach gun?" (its not a coach gun...), "Nobody shoots them except guys who like shooting thier grandpa's old gun," and "is that gun safe?"
