Although it can be more about styling/graphics and weight.
Campagnolo Chorus shifters have no sexy cut-outs in the brake blades and say "Chorus"
Campagnolo Record shifters are identical but have two sexy cut-outs in the brake blades and are stamped "Record" but weigh the same as Chorus.
Campagnolo Super Record shifters add a third sexy-cut-out, change the label, and actually weigh 7 grams less because they have different rear ratchets (but are otherwise identical).
This was a lot more confusing before Campagnolo started putting group names on components during the transition from C-record to ergo era.
