Some would say it does matter, that a more gradual choke constriction plays a role in improving patterns. Pretty much every long range choke is an extended choke, maybe they're right.
Well, now you're talking about something completely different: The specific geometry of the choke, not just its mounting location.
The bottom line is still that the performance of any choke on any single gun varies. There is no blanked way to state that Choke X is good and Choke Y is bad. Everything is down to the combination of choke, load, and shotgun and how they work together.

IME with Brownings, Berettas, & Remingtons, they all shoot turkey loads better with extended choke tubes than they do with flush mount tubes. Others I know with different brands report the same results.
