I'd previously had a first gen 10sp record build that was really nice, currently have a 12sp Record ergo levers with all chorus drivetrain and its the nicest feeling group I think I've ever ridden. Granted the frame is something special too and the overall build is amazing but the group isn't a let down for the whole build. I'd assume super record is just that much nicer but kinda like above, if I started hitting super costs I'd probably consider going electronic.
