I just got an Epsom + Z1-6 Travelcard on my Southern Key card. It seems to operate gates as fast as Oyster, and the journey history shows up on the web page within half an hour, rather than next day for Oyster.

I've travelled around with it quite a bit in the last few days. The only problem I've had is the gateline at St Pancras Low Level not recognising it.
