I have both the ported and unported 1895G models. I honestly can't tell the difference in report when I'm shooting it. I am told by those next to me that the ported is a little louder though. Still quieter than a short barreled AR and most hi velocity centerfire bolt guns.
I also don't notice any measurable difference in recoil. Over the chronograph the loads typically are within 20 fps of each other. I wouldn't not buy one because it is ported but given the choice, I take my unported 1895GS hunting the most.
