Depends on the Ducks and Clays course. One near me most of the top O/U shooters use Skeet chokes. Ducks over decoys open chokes can be very useful .

Personally I prefer tighter choked SXS guns, but there is a place for open Cyl barrels . I have a Parker lifter Cyl both barrels and it's fine on many Clays courses.

Pattern it before you make up your mind.
