I depends.
A best game gun was made and choked as the man who ordered it specified. His needs and preferences were what dictated the chokes, as they did all other options.
Off the shelf guns were intended to be selected and used as they stood and were tools intended for a variety of uses. A lot of British cheap boxlocks were made I.C and Full because it gave the option of a close range or a long range shot - either extreme.
I find guns easier to sell with some choke in them as that is what most customers want - but many ask for them to a be altered to suit them. It does not affect the price of the gun, just its desirability to some people.
