The SR shifters don't offer a thing, other than the name and cutouts in the brake lever.
I think the SR shifters just look cool but if there is a significant cost difference, then I would just go with Record. My local bike shop tried to convince me to go with Chorus on everything. They said that I wouldn't notice the difference.
