Just surveying opinions.

I've seen that flush chokes are more a pain to tighten than extended. I don't really know how often one should tighten a choke though.

Any validity to the gimmicks of porting and spiraling on extended chokes?

The slight (~1/2") elongation on an extended choke could provide a boost during trap and ranged shooting. Thoughts?

Whenever they start to come loose. By using a thick gun grease or Never Seize, that should be minimal

NONE whatsoever, even more of a stupid gimmick than barrel portnig

How so? What it DOES do is let you change chokes easily without tools, it lets you ID what choke is in there more readily, and it helps protect the muzzle of the barrels from dings in case of an OOPS

This is the only advantage I can see and the only reason I use extended chokes in my guns.

Keeping choke tubes tight is a non issue. Check them after each round. If they don't stay in after 25 rounds, something else is an issue.

Pattern wise, they are no better or worse than the flush tubes. Variations from manufacturer to manufacturer but nothing I would call significant.
 
Extended steel shot tubes keep the harder shot from peening the tube threads and the muzzle threads together.
 
I use exclusively extended tubes (factory extended invector) in my mossberg. It's easy in, easy out, easy to see what's in, no need for a tool that will get lost...

Yes.
 
Yeah, pattern testing would apply to all chokes individually. I would assume that the thought here was on whether ports help shot pattern which is a good point as some claim that patterns are blown apart by gas as the wad leaves the barrel. In reality my experience is that ported tubes are nicer because if they get stuck on by fouling a screw driver can be poked through for extra leverage...not because there's a noticeable change in pattern. My best turkey choke ever had no such fanciness. It was a gobblestopper I believe.

No. The additional half inch of length is not going to affect the pattern at Trap distances in any measurable way.

I have patterned all sorts of both extended and flush chokes. No difference in performance between the two types; the critical dimension is actual constriction, not what the name says. I did get some extended thinwall chokes with the constriction beyond the muzzle for shooting steel or other hard non-toxic shot through my SxSs, and they all worked as expected also.
