>>For those of you that have at various times owned BOTH- what did you settle on?<<
Like many of us here, I have both. Started out with O/U but have switched over to autos for clay shooting. Mine are Benellis, so it has nothing to do with softer recoil. I just like the way they perform, and rarely use an O/U anymore. Eventually, you'll probably end up owning both, and will make your own decision as to which you like better.
