I'm running a Chorus group with KMC SL11 chain on the winter bike which has been fiddled with once since installing in January (Owing to cable stretch).
I've also got Super Record with another company's cranks on the posh bike. This runs a Campagnolo chain at present but will be switched to a KMC as the chainrings and cassette are also due for replacement. The shifting has always been precise but then this bike does receive more attention per distance ridden compared to the other.
