I have the three 16 gauge makes and models you listed and in my opinion i would pick the 16 ga A grade Fox. Not a better or sleeker looking or handling American 16 side by side has been made than the Fox. I have 0 frame Parker and it has larger frame than the Fox.Smith fw has a very nice small size frame also. Parker probably better workmanship but not design. Just my opinion and i love them all! Bobby
