I have had O/U shotguns for 35 years. A year ago, I bought a CSMC RBL in 20 ga. And Six weeks ago, I found a Merkel 147E in 16 ga.
I have shot the 20 at clays and doves and some game farm birds. The Merkel has only been shot at clays so far, but it will get some dove and pheasant shooting this fall.
I am not a top end shooter, but I am a pretty decent shot.
I seem to shoot both the SxS guns very well.
However, if I had to have one or the other, rhe O/U guns would win out.
