The early Ergo shifters were shared by both groups, so no difference there. A few grams of weight all around on the other components, the 'hidden' fifth crank arm on the Record if you like the aesthetics, sunken spoke holes on the Record hubs, but as far as noticeable differences in use, I doubt you'd feel any. The Chorus "functions" just as well.

Later resale, if that's a factor? The Record, being the highest level group, will probably continue to command a premium over the others, and the differential will probably grow over time. Just my opinion.
