Single triggers do not negate barrel selection....a non-selectable single trigger would.
Speed and ease of selection with a single trigger can vary.
DTs can result in issues with gloves and may give the hunter too much to consider at shot time and in switching from single to double triggers but...drawbacks of any actual importance?...no, not really.
Chrome-lining does not make a barrel safe for steel shot....especially in a two-row.
Many "modern" 12 SXSs are chambered for 3" shells...likely too many 12 SXSs are chambered for 3" shells.
SXSs are pretty much equal in going boom if in the same price bracket and if breed blindness is factored into the answer.
Fit and finish can be the unimportant sticker with balance, steel treatment and triggers issues of more importance concerning purchase and use. There will always be scatterguns that have a history for strength, value, tradition and more....one simply makes a choice and adjusts as necessary later.
I will say that if one truly likes any gun, the odds are that he or she will shoot it well enough for government work....if they try earnestly, that is.
Though having their own particulars, the modern-ish BSS or SKB have a good reputation for toughness and practical bird swatting.
However, there are many, many offerings that fit the bill as well, especially re use in a pheasant field.
"Best" is a rather unimportant consideration.
Other than the most inexpensive market-fillers, they all work reasonably well if the gun matches the shooter and volume shot falls short of a trainload of cartouches.
