Joe Hunter nailed the extended choke tube issue for you. My reply is regarding the claimed benefits of ported choke tubes.
I have found that porting generally makes shotguns louder and more difficult to clean. Before owning a ported shotgun, my oiled wipe down cloths I used to just wipe the gun down after shooting but before casing the gun, seemed to last forever. But with ported barrels those wipe down cloths get filthy fast, then you're just smearing the filth over the rest of the gun. Then when the gun is home and being cleaned, the porting is an additional cleaning detail.
I understand the theoretical benefit of barrel porting minimizing barrel jump between shots on true doubles. But not being a highly ranked competivie shooter engaged in big money shoots, that "benefit" does not provide enough return to justify the disadvantages for me. More importantly for you though, barrel porting and ported choke tubes are not an apples to apples comparison. Ported choke tubes are usually ported 360 degrees, while ported barrels are not. I doubt that ported choke tubes do anything to significantly minimize muzzle jump to the degree that barrel porting may.
Depending on the angles utilized to port the choke tubes, I suppose scientific arguments based on the laws of physics may be made to support a claimed benefit of lessened perceived recoil. However, if recoil is the issue, major and significant recoil reduction is realized by reloading the shells down in both the amount of shot thrown and the velocity of the shot as well, while yet remaining effective loads for clay birds.
Again, another gimmick from manufacturers to charge more money for ported choke tubes vs nonported tubes. Also, another reason to convince folks to put away their "paid for" choke tubes and spend more money for ported choke tubes.
Ported choke tubes do look cool though to many shooters. Hey, it's your money and you should get what you like. I was just trying to give you perhaps a fuller picture enabling you to make a good decision for you.
I personally do like the extended but not ported choke tubes, as they are much faster and easier to change out, without needing a choke tube wrench to do so.
