Some tubes, for example Winchester, Mossberg and some others are fairly short. At least in comparison to those used by Remington, Beretta, and others.
Just for size reference all are 20 ga.
The tube on the right is a standard Winchester/Mossberg style. The middle tube is a standard Remington tube. But while the threads are far different Benelli, Beretta and many others are the same length as the Remington tube. Both the middle and right tube fit flush with the end of the barrel.
It seems logical to me that the longer tube will have a more gradual choke constriction and should give better patterns. But I've never seen any data, even discussion to support this.
The tube on the left is a Remington turkey tube with an extra full choke. The extra constriction is OUTSIDE the barrel on these. It is my understanding that a choke that tight inside the barrel could lead to split barrels. But I may misunderstand the concept.
I don't currently have any, but these types of tubes extend past the barrel; it is my understanding this is primarily to be able to quickly change the tubes with no tools.

Two questions
#1 Are the longer tubes such as those used by Remington better than the shorter tubes.
#2 If #1 is true, would someone benefit by using the longer tubes shown in the link over the short tubes.
