Porting is the biggest scam going; however if the gun you really wants comes with it, then learn to deal with it. It DOES increase noise, especially to folks on either side of you and does nothing to reduce recoil or muzzle climb. The only worse possibility is the ported choke tube.
Get the gun if it fits, if you have other possibilities, try them to see which one works best for you. That means actually shooting those models before you buy if possible
