Most of it is nostalgia Stan.
It's a link to the great master designer, so in that aspect it's an American gun.
They had a lot of handwork and the barrels are not monobloc.
The half pistol grip stock appeals to many, me included.
Mine is a plain 12 gauge field gun and I do enjoy it but then I like them all. As far as the action and ejectors, I don't find anything real special there except the part about how I never remember how sharp the ejectors are until I get a finger nicked catching shells. Happens every time.
The 20 gauge Superposed has remarkable dynamics, and the 20 gauge version of the Citori is essentially the same handling wise.
I consider my 20 gauge Citori XS Sport model to have the best overall dynamics of anything I've ever used to date including the 20 gauge Italian guns.
It's a direct descendant of the Superposed.
I'm certain you would enjoy a Superposed should the opportunity present, especially a 20.
