My last choice would be 16 gauge. Most are built on 12 gauge frames, so get the 12. 12 gauge is readily available everywhere! 16 is not! The 12 can be had in cheaper and lighter recoil loads than a 16. What you can do to a 16 to get it to recoil less, you can do to a 12. Between 20 and 28 in optimum loads there is little difference. Between the two I would pick the 20 because of availability of cheap ammo and the option of 3 inch. If one patterns the whole lot of gauges, it is obvious that only one often throws a less than game getting pattern at normal range. That is the 410.
