Fun topic. There has been enough varied responses to prove one thing: every constriction has a useful purpose. There is no correct or incorrect "one size fits all" answer. I am perfectly happy using my cylinder bored guns on quail but feel very inferior pass shooting geese with anything but a full choke. Incidentally, I grew up in a time when a full choke was the only manly boring to use and it was a hard habit to break but glad I did.

Sorta reminds me of being asked what is the best fly to use on a trout stream. The best answer is "whichever you have the most confidence in".
