It's all a combination of fit and how much you like to clean your shotgun.
Fit should be first and foremost. A shotgun that you shoulder with your eyes closed and then open your eye you should be lined up with the bead almost perfectly. That takes a lot of guess work out of it.
Gas autos need to be cleaned a bit more often, berettas seem to not need as much cleaning as say sx2s and sx3s style gas auto. Benellis can take a beating but have more recoil then gas autos. Depends if you shoot 3.5" a lot more often.
We've shot sx2s, browning golds, SBE2s. Vincis, super vincis, but now sold all of them and just run original SBEs. They shoulder us perfectly and work well for us. They shoulder like a nice 870 just semi auto.
