The single trigger switching mechanism is a pretty delicate item, a spring loaded pendulum. When your building an inexpensive mass produced double gun it isn't where they put any extra effort in. They are hard to repair when they go out of sync. Two triggers are just plain reliable.
The three biggest problems with inexpensive over/under's or sxs's are the single triggers, soft or brittle fireing pins or barrel regulation, you have to cut corners somewhere to sell for half the price of bottom end well made shotguns like a Berretta 686, or Browning Citori..
