For me you have forgot the most important peice of the question, WHAT AMMO? If you have ever considered using Federal you will imediatly be told no ported stripper chokes. So no Kickes orPattern Master. Don't know the others. I would go with Carlson's extendedas well. I recomend you visit the Beretta website store and look at their extended choke tubes if you have not already.
