My recommendation is to pick the gun you shoot best, that's more important than gauge or choke.
YES! But that does not mean which gun you shoot best on Station 8 skeet or trap.
Go to a skeet field. There is a center-stake both the low house and high house birds fly over. Stand at least 30 yards back from that stake and shoot high house birds. Whichever gun produces the most solid hits, take that one.
I carry a 20-ga. because it is light and I am shooting flushed birds over a pointer. For late-season jumped birds I would want a 12-ga. loaded with a ton of #5's and choked modified or tighter.
