You're trying to chose between two of the best available in that $$$$ class - With the Citori the best-selling O/U in the US.
At this point, the choice would be highly subjective, like choosing between GF's or car colors - whichever YOU like best.
After all, it's your money we're spending.
I happen to prefer Beretta's, due to the shallower action (The Citori is deeper, ala Superposed).
I know you want a 12ga, but since I switched to 20ga for all my shooting over a decade ago, I much prefer the scaled-down 20ga Beretta frame.
IDK if the 20ga Citori is on a scaled frame, or not.
