I went through the 16 gauge thing in the 80's and well into the 90's. Then I got over it. I realized it offers nothing over a 20 gauge in today's loadings, even moreso when you factor in the 3" 20. Maybe 60 years ago, but not today.
Today, the 16 gauge is a purely emotional choice, and I understand that 100%. Sometimes, it is a situation of choosing the gun, not the gauge, where you say "well I love this gun, even though it's a 16, and I'll take it anyway". All things equal otherwise, you would have really preferred a 20. Not necessarily every time, but more than not.
And I would not rule out owning another one. I still have my Dad's 16 ga Model 37 Ithaca that I grew up shooting and haven't shot in 50 years, but I certainly don't want another 16 at this point. Good luck and good shooting to all those who do.
