You have to decide on what you like. I switched to O/U's for almost all my shotgunning 36 or so years back. I agree if you get a ported gun it's very noisey but 26 or 28" non ported noise is a non issue in the blind or anyplace else.
When going to an O/U for hunting the there are a couple of factors you have to consider. Just how good a wingshot are you and gun weight. If you are in the camp that you need HEAVY and FAST loads to bring you're quarry down the O/U might not be the right choice. Shooting a light O/U with some of the loads available today is not a pleasant experience, heck even thru a gun like a standard Citori coming in at just a few onces under 8lbs in 12ga. and under 7lbs in 20 ga. will rock your molars.
Only you can decide what is right for your hunting.
