With modern screw-in chokes those 2 inches (+/-) mean almost nothing.
Best advise - Buy "extended" screw-in chokes (only way to fly) !
Longer barrels have a longer sight plan and help develop a good follow-through.
Shorter barrels are better for the field and longer barrel are better for shooting clays IMHO.
