Shotgun Recommendations

Hi everyone, I'm looking to purchase a shotgun for turkey and waterfowl. I've narrowed my list down to the following and I was wondering if anyone had any thoughts/opinions on these.

• Girsan MC312 Semi-Auto Shotgun
• Stoeger M3500 Semi-Auto Shotgun
• Benelli SuperNova Pump-Action Shotgun
• Winchester SXP Waterfowl Hunter Pump-Action Shotgun
